Google Buzz: Not fit for purpose

Please see update at bottom of post!

There has been, ahem, quite a bit of buzz about Google Buzz since they started rolling it out across the Gmail network a few days ago. I first saw an invitation to it when I logged into my inbox yesterday evening. Being curious, I accepted Google’s invitation to try it out, but fairly rapidly started to think that perhaps it was a bad idea.

My problems with Buzz are twofold: Firstly, it sits in Gmail, both as a menu item under my inbox and as live messages in my inbox. Secondly, there are some serious privacy implications that Google appear to either have ignored or not thought about. Either explanation is a poor show, frankly.

Buzz off out of my inbox!
I have written and spoken before about the problem with email, but for those of you unfamiliar with my views I shall summarise: Email is causing significant problems for people, not just because of the volume of email we get these days but because dopamine circuits in our brain encourage us to seek new information and cause us to check our email more often than we realise. Every time we check email, we waste about 64 seconds getting back into doing what we were doing before. Some people check email every 5 minutes. That’s an 8-hour day each week that we waste in mental limbo. Email is a significantly counter-productive tool yet it’s our default for almost all communications.

By adding in a new source of random reward – Buzz – Google have made their inbox even more addictive and unproductive. Not only do you have a new unread Buzz messages count to lure you into checking and rechecking, Buzz also tangles up Buzz replies with your email in your email inbox. Whilst that may seem sensible from an engineering point of view, or for someone whose inbox is quiet or beautifully organised, for me and the many people like me for whom inbox is a daily struggle, this is a disaster. I just do not need extra fluff filling up my inbox.

Privacy issues
For me, this mess of an inbox would be enough to put me off Buzz, but it gets worse. Google have historically not been great at doing social stuff. They are really great at their core business, which is search and serving ads against those search results. They also excel in some other areas, such as document sharing. And yes, I even appreciate the use of labels instead of folders in Gmail. But social stuff seems to be a bit beyond them.

Google Buzz lays bare Googles social weaknesses, illustrating the lack of thought given to potential social problems caused by their design and engineering decisions.

Privacy problem 1: Google Buzz exposes your most emailed contacts
Nicholas Carlson pointed this out in his Silicon Valley Insider piece, WARNING: Google Buzz Has A Huge Privacy Flaw:

When you first go into Google Buzz, it automatically sets you up with followers and people to follow.

A Google spokesperson tells us these people are chosen based on whom the users emails and chats with most using Gmail.

That’s fine.

The problem is that — by default — the people you follow and the people that follow you are made public to anyone who looks at your profile.

In other words, before you change any settings in Google Buzz, someone could go into your profile and see the people you email and chat with most.

This is a significant problem. I use my Gmail account for business and personal email, so many of my most-emailed people are not my friends but my clients. It’s not appropriate for Google to expose my clients like that. I maintain a client list on my site, but that’s at my discretion and doesn’t give away individual names and email addresses. Google Buzz could.

My email contacts list is not a social graph. It is not a group of people I have chosen to follow, but is instead full of people with whom I have a (sometimes very tenuous)professional relationship, as well as my family and some of my friends. Interestingly, my best friends don’t email me very often, so they do not show up as a part of my Buzz following list.

This answer to this is to go to your Google Profile and uncheck the tickbox next to “Display the list of people I’m following and people following me”.

Didn’t know you had a Google Profile? Nope, me neither! God knows when it was set up, or whether I agreed to it at some point in the past without realising what I was doing, or what. My friend Kevin Marks reminded me that he nagged me into creating a profile when Google first got them, which explains why I forgot all about it! But still, now I know I have a Google Profile I can give it the information I choose to.

Privacy problem 2: Poor default settings and no central control panel
Carlson goes on:

A Google spokesperson asked us to phrase this claim differently. Like this: “In other words, after you create your profile in Buzz, if you don’t edit any of the default settings, someone could visit your profile and see the people you email and chat with most (provided you didn’t edit this list during profile creation).”

This is appalling behaviour by Google. It’s well known that users tend not to edit their default settings. The people currently playing with Buzz may well be early adopters, more experienced in the ways of the web and more curious about settings and defaults. But you can guarantee that most people will accept the default settings as they are, without realising how much information that they are exposing to the world.

When you first join up to Google Buzz, you get a screen that shows you the people you’re automatically following, and who is following you. It doesn’t make clear that this information is visible to others, nor is it clear how to change the settings. If you go to your normal Google settings (at least for me) there is no ‘Buzz’ tab where I can manage all my privacy settings. Instead you have to ferret about in the interface in order to find the different privacy settings.

This is just not good enough. Right now, I can’t even find half the settings that I saw earlier. I found them through clicking on all the links I could see until I got to the page I wanted: This is the sort of usability mistake that Google should not be making.

Privacy problem 3: People can hide themselves from you
One of my followers is anonymous to me.

Google Mail - Buzz - Followers

This is completely appalling. I should be able to see exactly who is following me, and not have them be able to hide themselves from me. The opportunity for abuse here is huge – ex-boyfriends stalking their ex-girlfriends, bosses spying on their employees, random internet trolls watching their victims.

Anyone can get my email address – it’s out there on the web. It has to be, because I’m a freelance consultant and people have to have a way to get hold of me. This means that anyone can hide their profile and I won’t know who they are or why they are following me on Google Buzz. This is creepy in the extreme.

It also means that I can’t block that person. In order to block someone, you need to go to your follower list, click on their name and then click ‘Block’.

Blocking someone on Buzz

If I can’t see a follower’s name, I can’t go to this page and I can’t block them. Huge fail.

Privacy problem 4: Mobile Buzz can publish your precise location, but gives no option to make it fuzzy
If you have a browser on your phone, you may be able to use the mobile version of Buzz. When you open it up, it asks if it can use your location. Say yes to this, and your precise address will be published at the bottom of every Buzz you create. It doesn’t give you a choice in terms of how detailed you want to be, you can’t say ‘London’ or ‘UK’, it just determines your street address to the best of its ability and uses that.

This issue was highlighted by Molly Wood over on Cnet, and is as unhappy about it as I am. Molly has an Android, and her experience was this:

When you first visit the mobile app on your Android phone and attempt to post something, you’ll be asked whether you want to Share Location or Decline. The “Remember this Preference” box is prechecked too, so be sure you’re ready to have everyone know right where you are, whenever you post to Buzz. At minimum, uncheck the Remember button so you can decide whether to reveal your location post by post.

On the iPhone, there’s no “Remember this Preference”, so you are asked every time you open the site. You can turn location on or off on a per-Buzz basis very easily, so it’s not as bad as it sounds like the Android is, but the lack of choice about level of detail is dreadful.

If you do publish your location, you are not just publishing it to those people following you on Buzz, you are also, by default, also publishing it to everyone who is geographically close by. The ‘Nearby’ tab on the mobile Buzz site gives you a list and map view of everyone who has published a location that is within a certain distance. Again, this is fine if that’s what you want, but it shouldn’t be the default. You can, on a per post basis, set your privacy settings to “private”, but you don’t seem able to set that globally via the iPhone.

Once you have published your location you have to delete the Buzz in order to delete your location. You can’t just strip the location off the Buzz.

What’s also annoying is that it asks to use your location every time you open the site up. And every time you open up the Buzz Map. Every time. Lord, that is a real buzz killer.

(Molly flags up some other issues too: The use of photos from her Android that she hadn’t uploaded, and the revelation of her email. Her post is worth reading.)

Privacy problem 5: The opportunities for spammers and PR hacks
Jennifer Leggio has already had PRs spamming her via Buzz (on page 2). Oh dear lord, what a grim thought.

[T]he brand spamming and public relations pitching has already started. It’s bad enough that a lot of these people have my email address, but now they can buzz me just by adding me. (Whether I add them back or not, I found. Was this a glitch?)

The idea that Buzz is going to make me more available to PR people and to spammers, against my will, is not one that fills me with joy. I already get heaps of crap press releases in my inbox, I do not need more of this stuff cluttering things up. The true spammers aren’t there yet, but they will so find a way to abuse Buzz and make the whole thing a horrible experience. And right now, Google seem to be making it easy for them.

Privacy problem 6: Buzz automatically links you to other Google properties like Picasa and Google Reader
Jennifer says:

If you are using Google Picasa and Google Reader yet are not wholly aware of Buzz, you may not realize what you are publishing and promoting to your Buzz stream because you may not know it exists.

Again, would it be so hard to hold off automatically publishing stuff to people’s Buzz streams and make them go through a configuration process before they start publishing anything? Of course, that wouldn’t suit Google, who want as many people to be using Buzz as soon as possible. They don’t have a new tool here, they are just integrating Jaiku, whom they bought in Oct 2007, into Gmail. (Wait! What? It took them over two years to think of this?) So they don’t have a really compelling reason for people to change from Twitter or Facebook or FriendFeed. Buzz is not a killer app, it’s a mess. A TGF.

In conclusion
I haven’t even begun with the usability problems Buzz has. How poorly considered the interface is. How annoying it is when your Buzz stream is flooded with someone’s Google Reader output. But I do have a cure:

Go to the bottom of your screen and click “Turn off Buzz”.

turn buzz off

That should pretty much solve the problem. Google can get back to me when they’ve hired someone who actually understands social functionality and, y’know, people, and has fixed the awful usability and privacy problems. As Steve Lawson said:

There’s a reason why I don’t keep a ‘who I’ve emailed this week’ page going on my blog, and it’s not just cos it would be dull as shit.

UPDATE: 12 Feb 2010, 10am
Google have responded very rapidly to users concerns regarding Buzz. In a blog post on the Gmail Blog comes the news that they are making changes to the way that Buzz works and will be rolling those changes out soon.

The changes they are making are:

1. More visible option to not show followers/people you follow on your public profile
2. Ability to block anyone who starts following you
3. More clarity on which of your followers/people you follow can appear on your public profile

My advice to all new Buzz users would be:

  1. Edit the default list of followers that Buzz suggests when you first join the service. Make sure that you are only following people you want to follow.
  2. Decide if you want that list to be public. If you are in any way unsure, make it private.
  3. Keep an eye on who is following you, and use the block functionality if you find someone following you who makes you uncomfortable in any way
  4. Edit your public profile page and make sure you are happy with the information it displays. The minimum Google will accept is a name.

Having used Buzz already, I can’t check what the defaults are on initial sign-up now, but I’m hoping that Google has made some better choices about default levels of privacy. It would be better if Google doesn’t automatically tie Buzz into its other properties, but asks people to choose that up front. It will certainly be good to be able to see (and block, if I choose) everyone who is following me, not just those with public profiles.

There’s still no word on fuzzy location on the mobile app. My personal preference is not to use geolocation apps, but that’s just my own squickiness. I might use it more if I could set the level of detail in my location, e.g. “London” as opposed to a street address.

Now, if Google gives us the option to spin Buzz off out of our inbox and into a separate app, I might be more inclined to give it another go. But keeping it in the inbox is still a dealbreaker for me. I have enough problems managing my email already, I don’t need Buzz to add to the cognitive load.

I doubt that Google will separate them, though. Just read their opening paragraph where they coo over how many users they have. That’s why they did it like this: It gave them an immediate user base that they probably would not have got if they had launched it as a stand-alone service. My friend Max said to me on Twitter yesterday:

Wave is a separate app that should have been part of GMail, Buzz is part of GMail and should have been a separate app…

And I think he pretty much nailed it there. Buzz still feels uncomfortable in my inbox, but at least Google are making some progress towards clarity and better privacy controls for users. Here’s hoping the solve the other problems soon.

UPDATE: 12 Feb 2010, 1pm
Jessica Dolcourt of Cnet has put together a very clear guide on how to opt-out of Buzz. Turning it off doesn’t purge your profile or stop people following you, so a few more steps are needed.

Time to sign up to Ada Lovelace Day 2010

Last year, over 3500 people pledged to support Ada Lovelace Day, the international day of blogging to celebrate the achievements of women in technology and science. Over 1200 people added their link to our map mash-up and we got lots of coverage in the national press and even appeared on the BBC News Channel. Women’s contributions often go unacknowledged, their innovations seldom mentioned, their faces rarely recognised. We wanted you to tell the world about these unsung heroines, and you did. Thank you!

But our work is not yet done. This year we want 3072 people to sign up to our pledge and to write their tribute to women in tech on Wednesday 24 March. We have 197 signatories so far, we just need another 2875, which is where you come in. Please sign the pledge and let all your friends know about it.

It doesn’t matter how new or old your blog is, what gender you are, what language you blog in, if you do text, audio or video, or what you normally blog about – everyone is invited to take part. All you need to do is sign up to this pledge and then publish your blog post any time on Wednesday 24th March 2010. If you’re going to be away that day, feel free to write your post in advance and set your blogging system to publish it that day.

Cars: There’s an app for that

Suw and I are taking two weeks off. Most of the time, we’ll be here in London enjoying a holi-stay. I might engage in some deep-thought blogging after recovering from a really too busy 2009. In the meantime, I’ll just engage in a little light coolhunting.

Someone recently was picking my brain about the future of in-car technology. I think that one of the knock-on effects of the iPhone is that people will expect apps and add-on services in a wider range of consumer electronics. Cars will not just have on-board computers to manage the engine but also on-board computers to navigate, entertain and inform much as we would expect in our home.

Hobbyists have already been adding these kind of systems to their cars for years, and Prius drivers love to hack their hybrid cars. High-end cars have complex environmental and entertainment systems, but we’re starting to glimpse how these activities will filter into the mainstream.

Satellite radio services in the US have been using some of their surplus bandwidth to provide information services, and with 4G data services such as WiMax and LTE service expanding in the next few years, mobile data will provide the kind of bandwidth that we’ve previously thought of as restricted to DSL and cable. Faster wireless connections will bring new forms of entertainment, expand the use of web services and provide new opportunities for information providers.

GigaOm has a great post on a prototype system in a Prius.

As a journalist, the question is whether news organisations will let another opportunity slip by them.

Visualisation for news and community discovery

I think that visualisations and interface innovation hold great untapped potential for journalism, not only helping journalists and audiences to see trends and understand complex sets of data but also as a tool that will dramatically improve news site usability. The last few years have seen a lot of innovation in visualising data with the advent of mash-ups and easier visualisation tools from Google, Many Eyes from IBM, etc., but there has been too little interface innovation for news websites.

By and large, news websites still reflect their print heritage. They make the classic mistake of rigidly reflecting their own structure while ignoring the semantic connections that cross desks and departments. Most news web site interfaces obscure the vast amounts of information we produce as journalists. Good interfaces go beyond design and search to issues of information architecture, user experience and discovery.

I believe that interface innovation can unlock the power of technologies, helping them break out of a small group of technically adept early adopters to a much wider audience. The Windows-Icon-Mouse-Pointer interface helped open up computers to a much wider audience than when command line interfaces were dominant. The graphical web browser helped unleash the power of the world wide web. In 1990, when I first used the internet, I had to learn arcane Unix commands to even read my e-mail. In August 1993, I used the seminal web browser Mosaic for the first time in a student computer lab at the University of Illinois, where I was studying journalism and where that groundbreaking browser was created. I instantly realised that the web browser would become a point-and-click window to a world of information, communications and connection.

I’ve been interested in interface innovation since the late 1990s when I first saw the Visual Thesaurus from a company then called Plumb Design, now called Thinkmap which showed the connections between related words. The company did even more impressive work for Sony Music and EMPLive, an online exhibition for Microsoft co-founder Paul Allen’s Experience Music Project. In many ways, the work was way ahead of its time and sometimes ahead of the capability of the internet. The projects used advanced interface concepts more often found in CD-ROM projects of the day than the internet. One of the things that impressed me about especially the EMPLive project was that it allowed virtual visitors to the navigate the music collection a number of ways, whether they were interested in time, genre or a particular artist. The presentation also showed relationships between elements in the collection. I like Robin Good’s description on the Master New Media blog of Plumb Design’s work:

The original goal at Plumb Design was to create dynamic interfaces to information systems that reveal interrelationships often obscured by conventional methods of navigation and information display.

In many ways, Plumb Design showed what was possible with data, semantic analysis and rich interfaces more than a decade ago.

While interface innovation has not been an area of focus for most news sites, thankfully we’re seeing some tentative steps forward after a post-dot.com crash period of stagnation. Slate has launched a service called News Dots. Chris Wilson describes it like this:

Like Kevin Bacon’s co-stars, topics in the news are all connected by degrees of separation. To examine how every story fits together, News Dots visualizes the most recent topics in the news as a giant social network. Subjects—represented by the circles below—are connected to one another if they appear together in at least two stories, and the size of the dot is proportional to the total number of times the subject is mentioned.

Like EMPLive and the Visual Thesaurus, News Dots helps show the interconnection between stories. The feature uses Calais, “a service from Thompson Reuters that automatically “tags” content with all the important keywords: people, places, companies, topics, and so forth”. Slate has built its own visualisation tool using the open-source ActionScript library called Flare.
Slate's News Dot project
It’s a good first stab, but Slate admits that it is a work in progress. I like that the visualisation clearly links to articles and sourcing information. I like that the dots are colour-coded to show whether the dot represents a person, place, group, company or ‘other’. I think there might be a possibility to better show the correlation between the tags, but as I said, this is a good launch with a lot of possibility for improvement and experimentation.

Another project that I think shows the potential of improved interfaces is the Washington Post’s visual commenting system called WebCom. As Patrick Thornton explains, it is a visual representation of comments n the site. As new comments are posted the web expands. Those comments rated highly by other commenters or those that spur the most responses appear larger in the web. The web not only allows for navigation and discovery, but users can comment directly from within the visual web interface.

Thornton says:

The commenting system was built in two weeks by two developers at washingtonpost.com. A front-end developer worked on the user interface, while a back-end developer created the database and commenting framework in Django. Because the user interface was built in one language — Flash’s ActionScript 3 — and the back-end in another, the Post can take this technology and put it on different parts of washingtonpost.com with different user interfaces.

Wow, that’s impressive in terms of turnaround time. Django is quickly becoming an essential tool for the rapid development of journalism projects.

Thornton points out that it doesn’t work on mobile browsers or older computers. I might quibble with the focus on most popular comments or comments that spur the most response; comments that draw the most responses can often be the most inflammatory or intemperate. Likewise, popularity often becomes self-reinforcing, especially when it drives discoverability as it does in an interface like this. I would suggest that a slider that weights other factors might be useful. A simple search or tagging system might help commenters to find threads in the discussion that interest them. Again, this is a good first attempt and, with the development time only taking a few weeks, it shows how rapidly innovations like this can built and tested in the real world.

It’s exciting to see these kinds of developments. News organisations are struggling during the Great Recession, but often these times of crisis spur us to try things that we might otherwise think too risky. Whatever the motivation, it’s good to see this kind of innovation. If this can happen during the worst downturn in memory, just think what we can do when the recession eases.

Will the Asus “Eee-Reader” be a sea change?

Lots of people were tweeting yesterday about the new Asus e-book reader which, we’re told, would be a form factor unlike any of the e-book readers currently out there. Due out, possibly, before the end of the year, it would be a foldable dual-screen reader which will let the user read a text on one screen whilst surfing the web on the other. It will be full-colour, with a soft keyboard on one of the screens. With a price tag of somewhere around £100, it could make a very compelling device.

But I fear there is a big, fat, juicy fly in the ointment. Neither Kevin nor I have been impressed with the software that comes built into cheap electronic devices. We bought my mum a little MP3 player a few years ago and whilst it looked nice enough and was within her budget, the user interface was nothing short of appalling. Even I had a few problems understanding how the thing was supposed to work and as far as I know, my Mum hasn’t touched the thing in months, if not years. And as for Kevin’s GPS device wrangling hassles, let’s not even go there.

We’ve also not been impressed by the Asus Eee PC’s operating system, Xandros. It’s not because Xandros is based on Linux, which we both use regularly, but because Asus’ implementation of Xandros makes it difficult for the casual user to install software not included in Asus’ package. It’s like Microsoft making it difficult to install anything but Microsoft-approved software on your laptop.

When it breaks, you need quite a bit of know-how to fix it. Kevin has spent hours working on a friend’s Eee, first getting it to run a Twitter client and then fixing a BIOS update that buggered things completely. Updates to the Eee change the location of user application preferences, which can then break shortcuts to user-installed software. That makes installing your own software challenging. This is something that users would be up in arms about if it were Apple or Microsoft.

The mock-up of the Asus “Eee-Reader” looks lovely and the price is certainly user-friendly, but will the software be? I have shied away from the other e-readers because a portable device of that size that I can’t write and check email or Twitter on is unappealing to me. The users interfaces of the devices I have played with have been at best clunky and at worse frustrating and proprietary software means users can’t install their own software (as far as I’m aware).

If, like the Eee PC, the Eee-Reader uses either a Linux or Windows variant as its OS, users will at least be able to customise their device to some extent (depending on hardware limitations and know-how). At the moment, netbook users who have the Windows machine actually have more freedom than those on a Xandros machine, because Asus have made it so difficult to install software on Xandros. If the Eee-Reader gave me that choice, I’d probably end up plumping for Windows, even though that comes with its own issues.

What might be interesting would be if it was capable of running Android. As Kev tells me, “people have some interesting hacks with Android.” I’ve never had a chance to properly play with Android so I’m not sure if I’d be keen on having it on my e-book reader or not. I would guess that ‘Hackintoshing‘ it won’t be possible; there are specific hardware requirements for a Hackintosh and as yet we have no idea whether the Eee-Reader will meet them.

My worst-case scenario is that Asus would produce some sort of proprietary OS with only limited functionality that users can’t add to. If Asus did that, they would be missing a trick – the success of Apple’s App Store shows that people want to be able to install applications of their own choosing onto their phone and that developers are willing to spend time creating them. If the Eee-Reader’s hardware specs mean that software needs to be specially developed or adapted for it, then Asus should use an OS that’s easy to develop for and create an open marketplace that encourages an ecosystem of applications for users to choose from.

The initial description of the Eee-Reader sounds attractive, but unless its software is usable and extensible it’s not going to tick the box for me. I can’t carry round a laptop, and iPhone and an e-reader; my back would never forgive me.

Why Identi.ca needs to look further afield than open source

There’s been a lot of buzz in the Twittersphere this morning – well, when Twitter behaves, that is – about a new Twitter-like service, Identi.ca. Launched yesterday, Identi.ca takes the Twitter idea and open sources it, and that alone makes it worth keeping an eye on not just because we can soon expect a world full of Identi.ca installations, but also because it means that business will be able to take the code and run it behind the firewall, finally bringing Twitter-like ambient intimacy to enterprise. (If any businesses are brave enough to experiment, that is!)

In my view, though, being open source isn’t going to be enough of a draw for most people. Even if you assume that the service will turn out to be stable, reliable, richly featured, able to easily import contact lists, and attracts the interest of third party clients like Twitterific and Twhirl, that still won’t be enough to draw people away from Twitter, unless Twitter catastrophically fails. Yes, Twitter’s having significant and annoying problems, but it’s important not to underestimate just how apathetic users can be when it comes to migrating from one social system to another.

What Identi.ca needs to do is to become a cross between Ping.fm, which allows you to posts to multiple social networks, and FriendFeed, which aggregates your output from a variety of tools such as Twitter, Flickr, and Del.icio.us… but with bells on. We need a ‘write once, post anywhere’ system, combined with an ‘aggregate and de-dupe’ system, so that we can all become tool agnostic. Such a system wouldn’t care where you wrote your update, it would distribute it to all the tools you use, and it would aggregate back responses from all your friends, regardless of which system they used at the time.

I think there are two key parts to such a service: De-duping will be essential if such a system is going to be at all usable. If you post the same message to Twitter, FriendFeed, Plurk and Jaiku, then I don’t want to see it showing up four times in my aggregated feed. Friend list management and grouping is going to be the other key issues. The tedious thing about Identi.ca – or any other such service – is recreating my Twitter friend list, or at least some part of the Twitter/Identi.ca friend lists Venn diagram. This is possibly where something like OpenSocial might come in very handy.

I doubt that such a tool would be simple, and relying on other people’s APIs creates multiple points of failure, but the nice thing would be that if I am posting to all ‘microblogging’ platforms and aggregating them all back again, it won’t matter if one tool goes down for a bit. If Twitter dies, but my update has gone to FriendFeed too, and then pushed back out to my friend’s account that they happen to access via Jaiku, who cares that one route in that network was out of action for a bit? On the other hand, if Identi.ca were to becomes that WOPA-AADD system, then you are rather creating a single point of failure… unless, of course, people were to run multiple installations as nodes in a Skype-like network, which would be possible with open source code. Just a thought.

Whilst I doubt that I’ll be deserting Twitter any time soon, if Identi.ca moves in the right direction it could really make a big difference to how we maintain our online presence.

TV Un-Festival: Sclipo

Gregory Gimi

Social network that allows people to share knowledge through video. 600 million people use the internet to find information and to learn. Learning on the internet is a very important one. Why Sclipo? Three phenomena:

– video became efficient, most of the learning you could do before was text based. So can see what you are being taught. Added quality of learning.
– web 2.0, user generated content. Not so much that people generated content, but that people looked at people generated by other people and find that attractive, e.g. Wikiepedia, YouTube. Without being recognised professionals. Adds efficiency to the process.
– social networking effect. very popular, and learning experiences depend on social networking.

Have different ways of browsing the video content, looking at videos that teach skills, through ‘Academies” which are channels, and skills channels which are companies demoing their products.

Everything from cooking to technology. Similarities with other websites, but we use more educational terminology. You can learn through two methods – looking at the video and then by webcam, so if I find someone who’s good at cooking and I have a specific question, the next level of learning is through a webcam, and this is what we call SclipoLive, so can request a class from that person.

[Demo of a live webcam teaching session.]

The webcast is automatically recorded, so can then be watched by other people afterwards.

Three models of academies: if you teach and make money then there’s a commission, if you don’t make money then add ads.

Q: Do you share the ad revenue with the person giving the class?

Not at the moment.

[Long discussion of how payment system could be built.]

Q. what licences, e.g. Creative Commons, can I use?

Publisher owns the content, the person putting the video up.

TV Un-Festival: Jonathan Tweed – BBC iPlayer Facebook app

Hackday – put iPlayer on Facebook, wanted to show the iPlayer team what they should be doing. People are too busy to watch TV. Times this week reported that usage of social networking site exploding and that this is going to have an impact on TV viewing.

When people aren’t watching TV they are either going out or going onto social networks like Facebook. Answer to this is to put TV on Facebook because that’s where people are – put your content where people can’t miss it. Problem – if they are not watching TV, how do they know which shows to watch. They trust their friends more than anyone else, so have to add social features so people can recommend things. Everything else has social features, but iPlayer doesn’t. So added social features to iPlayer, shows what friends are watching, and what they think of them, also have current pics on iPlayer, and last night’s TV. Provides a click through to iPlayer to download/watch the TV, so can also search iPlayer.

Can also add reviews, which adds to Facebook, and to iPlayer. That’s as far as it’s been taken so far. At the moment you have to seek out what your friends are watching but want to add in a notifier to tell you what your friends are watching. Going to add recommendations. Want to find out what you think, what do we need to add to make it compelling?

Should we be doing this? Other companies are doing similar things? Should the BBC host a site where users are reviewing its programmes? What does it need? What would make it use it? What’s the future for Facebook applications? Is it a fad?

apps.facebook.com/bbciplayer, but need to be on the iPlayer beta at the moment. Once iPlayer comes out of beta it can be on the directory.

Q: Have you thought about widgets?

Yes, we are. But this isn’t an official project. Did this for Facebook because we can’t do it on MySpace or Bebo, but will put together widgets for other sites.

Q: Why do recommendations by brand?

We’re going to do it but programmes, or by genre, or whatever you want.

Q: What about the ability to become a critic?

That’s a good idea.

Q: Can you recommend stuff that’s not on iPlayer?

No, because it screen scrapes the iPlayer site. Quit hard to get access to the internal BBC data but because this is hosted externally we can’t. Value in the application. Need to get more stuff on there and use other ways of finding it. Is it reasonable for the BBC to do this?

Q: Is this programmes or just clips.

This is full programmes.

Q: Is it worldwide.

Application is available worldwide but iPlayer is UK-only.

[Lots of discussion about possible functionality which I’m not going to transcribe, because I’m getting tired now.]

TV Un-Festival: Paul Cleghorn – Tape It Off The Internet

Designer by trade, made some screens of what he thought that a compilation of what TV was available on the web, and took a lot of user feedback and started a build from scratch, starting in March. Live with a new version launching in a week or two. Going to open up to beta users.

Core mission of Tape It Off The Internet (TIOTI) – like Wikipedia, start with licensed TV information, can add all sorts of things to it, video clips or photos or text description, fan fiction, production notes, etc. Indexing all stypes of TV. Started with BT because it was the only stuff out there, now also iTunes, Amazon, as well as Joost, TV-Links.co.uk, etc. Taking any format and gluing it all together.

Building a social network around it too, can invite fans, can recommend shows, use your peer groups as a basis for recommendation. Trying to get hte whole world of TV in one place. Still a bit hard for people to find what they are looking for, we are trying to smooth that process.

So look at a show, pull in licenced source, but let people add things, so there’s a photo gallery too, so if you saw these people at an awards show then you can draw in from Flickr. Build up user generated stuff around the show. If you find something related on YouTube, e.g. a spoof, or blooper reel or anything else, can add that too so that you build up a full resource.

Trying to connect it up with other services such as Facebook, using Facebook login and will pull in the ‘TV shows you like’ so you don’t have to repeat yourself.

Using tags such as country, and badges so that people can link through to, say, your Flickr page. Looking to open it up over the next couple of weeks. Has widgets.

Indexing stuff like Virgin so detect you have a Virgin IP and show you what they have available.

Being open as possible with user data so that people can take their stuff with them. Trying to cross-reference different sources to help the recommendation engine. Doesn’t seem to be a definitive TV microformat yet, so might make a new one or hijack one. And RSS feeding a lot of stuff, can get feeds for discussion, downloads, etc.

Q: Tivo patent could be an issue for season passes.

We’re not a recording service, we’re just showing information about TV, so we’re not doing season passes, because we’re just listing as many options as possible (unless that becomes unmanageable). But we’re not a recording service.

Q: Where do you licence the data.

From Tribune Services, mainly it’s EPG content, so weekly update with about 2 weeks of information. they have a 40 year archive which we’re using for our archives. Not doing a schedule-based aproach. Do want to skirt around the Gemstart grid patent. Better way to do it.

Q: What about the licensing of data that people put up?

We need to look at Creative Commons, atm, it’s standard terms and conditions, but not sure that’s the best way to do it. But that’s how our lawyers like it at the moment.

Q: You’re being respectful of other sites, but your competitors aren’t and are indexing more content. Is that a worry? E.g. Share.tv

So we index them but we don’t index YouTube because there are two many cats. Not uch reason for us to spend a huge amount of time filtering big buckets of video when others are doing that. We want to be the metaindex at the top.

TV Un-Festival: Ian Clarke

Degree in computer science and AI from Edinburgh, and designed a project to exchange info in countries where there is censorship. This became Freenet. Non-profit corp in USA, since 1999. 2 Million downloads of software. One of the things that happened with Freenet, even though it was designed as freedom of speech idea – was at same time as Napster – it was perceived as indestructible Napster as it was designed so that it couldn’t be shut down.

Has been thinking, how do you enforce copyright onlne, and the answer is that you can’t. Enforcement of c is about preventing people sharing information when they don’t have permission to. So if you can’t enforce copyright, what is the alternative?

Founded Revver in 2005, to help foster an environment of creativity online, want an ecosystem where creators can be paid for their work. Interested in online video, this was at the time when broadband was starting to make this possible, devised a way to attach unobtrusive ads to end of videos, release under CC no-derivs, attrib, licence, and share the revenue on a 50-50 basis with creators, or 40-20-20 if there was an affiliate, so produce financial incentive to share video.

A lot of the people you may have heard of use or have used Revver, e.g. LonelyGirl15 for about a year, ZeFrank. Almost every well known video blog has used Revver, except Rocketboom.

Whilst at Revver, got curious of how to figure out what people are interested in and show it to them. Not a new problem. Started to look at collaborative filters, basically a system which looks at your behaviour, perhaps what you buy on Amazon, and then recommends things to you that you might like. Amazon, NetFlicks. Problem is that they either work or scale – but they don’t do both. if they can recommend stuff well, they don’t scale, or they dumb down the recommendation so it can scale. Built a filter called Daedalus for Revver, and licensed it to Reddit.

Whilst working on this collaborative filter, noticed that collaborative filters need a lot of data before they can figure out what they are interested in. So Reddit needs people to use the website for several hours continuously. Real opportunity in online news space, with n otable exception of Reddit, no one was really doing personalised news, and those that were were using collaborative filters that are problematic, and the quality of user submitted news is extremely low. If you’re familiar by Digg, you’ll know what I’m talking about.

This was the genesis of Thoof. Alternative to collaborative filtering, figures out your interests more quickly, based on your behaviour, your browser, your approx. geographic location. There are generalisations you can make about mac vs PC users, or Firefox vs. IE, or based on geography. Built tech to recommend stuff to you, but if you see something on the website that can be improved, you can change it and fix it, although there is a voting step – you propose a change and if it survives the voting process it can be applied to the story. Raised a million dollars in seed foundation, launched in June, and traffic growing at 25% per week.

Using Freenet is like using a web browser, but slower – learnt that one of the key problems is that even when there is information available, that doesn’t mean that people will find it. It’s not just about accessing information that they know they want, but about finding information that will interest them once they know about it.

Go to URL in web browser, it’s easy to find out who’s hosting what. With Freenet, info is distributed through the network in a decentralised way, so unless an author chooses to reveal their ID, you have no way to know who they are. But threat model with Freenet at the time was that no one would know what people are doing with Freenet, but that’s not enough. What if you can be punished for just using the software, irrespective of what you are doing with it, e.g. China, so set about redesigning Freenet to use a darknet methodology, so that you could just connect to those people you know personally, so no one knows you are connected to Freenet, but through those people you become a part of a global network. Been working on this for two years, but working pretty well so far – lot of people don’t already have friends that are using Freenet so there is a way you can connect to strangers as opposed to friends if you choose to do that. Freenetproject.org

Q: Are there access points into Freenet, like SMS?

Not an SMS gateway to the best of my knowledge, are web gateways, but using a gateway is … you’re throwing away a lot of the benefit. To get the security, you have to be running Freenet on your computer. It’s not going to run on a typical mobile phone.

Q: You said it was friends of friends, if you try to keep cosiness amongst your contacts, how do you deal with infiltrators?

The only people who can cause problems for you are the people you have immediately connected to. So if your friend is stupid and connects to a government agent, that agent has no way to tell you are part of the network. Many Freenet users don’t care, because they live in the US or UK where they aren’t going to be jailed for this, and will connect to anyone. But we try to place it in the hands of the individual as to how much security they want. There’s a trade off between convenient and connected.

Q: What happens with people abuse the tool.

Any tool can be abused. But the freedom to communicate – if one person wants information and someone else wants to have it, that freedom is essential in a democracy. Our leaders are chosen by us, and in order to make effective decisions we need free information. So totalitarian countries spend a lot of money controlling their people’s ability to communicate. Any tool can be misused but the benefits outweigh the potential abused.

Q: How do people know who to trust?

When people are anonymous how do you know when to trust them? That’s a question that the internet in general gets, blogs etc. But at Freenet we address that problem with the concept of a Nym, an anonymous identity so anything you publish is signed by the nym, so you can link together discussions and content to the same person. Even an anonymous identity can build up trust. Similar to the WWW, a blogger can build up trust. This problem is not completely solved – what might be intersting to experiment with, and we may do it with Thoof in the future, and Thoof’s approach is to fix in a peer reviewed way which works well. What we’re likely to do in the future is to create a ‘web of trust’ so can build up trust based on performance. So if you propose a change and it’s rejected, that decreases your trust level, but if you propose a lot of changes and they all get voted through you’d get more trust. So maybe then stories you right are promoted more quickly, but the mechanisms within the site will get rid of it really quickly.

Q: Where are Thoof stories from?

You can submit anything that has an URL. YouTube, BBC article, anything. What goes on Thoof itself is a title, description and tags. Intention is that the title and description will be impartial and unbiased description of what’s being linked to, but the thing being linked to can be expressing an opinion. Can edit review, title, and even URL.
