Twitter Recently, actually for the past year, I’ve not been following anyone new on twitter. I use twitter as a work information stream, but I’ve been frustrated by the number of tweets unrelated to the work. Now I know that everyone uses twitter in their own way, and I also know some prefer to blend their tweets preferring the more holistic picture this presents. But for me it’s all about work, and Facebook is all about friends.

Open Notebook Science - Was talking with [Andy](http://scholar.google.co.uk/citations?user=kJKbD3MAAAAJ&hl=en) this morning re 'TV no longer commands our full attention' **[1]** and the work we are doing with the BBC. It was interesting to consider the outcomes of the paper in the light of the [attention approximation](http://staff.cs.manchester.ac.uk/~browna/publications/MSO-CHI.pdf) work, also with regard to the implication that there is an increased cognitive load and we know in HCI that this is often seen as a pejorative thing; and that we need to keep cognitive flow to a minimum.
