Focus in lifelogging and blogging

I recently read Sellen and Whittaker's excellent review of Lifelogging studies. Their key point is that, so far, prototypes haven't capitalised on what we know of how human memory works, for example
- that we store partial, associatively organised memories of events, rather than total, chronological  capture- that although we want to recall things, we also want to reminisce, and reflect on our memories
- and that one of our challenges is not remembering things from the past, but remembering to do things in the future.
Some interesting details emerge (for example, Gregory Abowd's finding that lecture recordings don't significantly improve students' grades; that whereas trials show meeting recording is popular with participants, it has never caught on as a business tool).

Sellen and Whittaker make the distinction between passive 'lifelogging' and active 'blogging' in which we choose what aspects of our lives to record, one of which is, apparently, food. TechCrunch post on recent funding for food blogging service, Foodspotting, commenting 'Don’t even bother arguing about it. It’s just the way it is'.

And so it would seem: in yesterday's Guardian Martin Parr was encouraging readers to photograph their food:
"When you are away, why not record all of the food that you eat? If someone has spent a lot of time cooking a meal, or if you're going out for a treat, photograph the food. You could make a series of each breakfast, lunch and dinner that you ate. That would be fascinating."

Indeed.
