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.
