Kevin: Steve Yelvington takes a post by my colleague Charles Arthur who observed that news is fungible and moves it on. He looks at newspapers from a consumers point of view, and asks why people buy newspapers. "The problem of fungible commodities is that open markets relentlessly drive prices down toward the cost of production. You want profit margins? Look for scarcity."

Kevin: My esteemed colleague Charles Arthur writes on his personal blog about why the fungibility of news means for the future of newspapers. In a word, he thinks that newspapers are screwed. The post paints a sobering portrait of the newspaper business. I think that a fair few clear headed people know where we're at, but I think the next step is to figure out where we go from here. News is no longer scarce. We're often chasing the same stories and produce a lot of the same content. We really need to ask what it is that we're producing of unique value for our audiences. The market is currently punishing journalists for not asking that question clearly enough.

Kevin: I heard from an attendee at Webstock that Bruce Sterling just seemed to be 'trolling'. I think it's interesting to hear alternative points of view and keep a healthy distance with complex trends like Web 2.0. Not sure that this was a cogent critique

Kevin: A discussion at BeebCamp on how the BBC should use Twitter. It's an interesting discussion that I am sure is happening in a number of media and news organisations these days on how (or if) they should use Twitter.
