Me and 3 other grads in my department have just started an accountability system where we've precommitted to send at least a page (or equivalent) of work to the others by the end of each day. I'm interested to see a) whether we keep it up past a week or so, b) whether it has a noticeable effect on productivity levels while we're maintaining it. (Obvious confound: part of the reason we've precommitted to this is because it's the end of semester and we all have tons of work to do. But hopefully knowing that I have to produce at least a page will help keep me focussed when I'm tempted to procrastinate)
