Kevin: Geoff McGhee has created a video report looking at data visualisation as a story-telling medium. It has examples of telling 'data stories', life as a data stream and exploring data and technologies and tools.

Kevin: Video from a recent event on data journalism at the Frontline Club in London. Features Simon Rogers, editor of the Datablog at The Guardian (friend and former colleague) and David McCandless, designer and author of Information is Beautiful. Really good note from Michael Blastland, freelance journalist and creator of BBC Radio 4's More or Less programme. He reminded journalists that they must interrogate official data and question how it was created.

Kevin: Excellent piece by Jemima Kiss, friend and former colleague at The Guardian, looking at how mobile and the apps economy is driving renewed confidence at UK online publishers. However, the report was thin on details about revenue, she noted. Good details on freemium, sponsored and single purchase apps.
