Update on the accountability system started about a month ago:it worked for about three weeks with everyone regularly turning in work, now I'm the only one still doing it. Lessons learnt: it seems that the half-life of a motivational technique is about 2 weeks. The importance of not breaking the chain (I suspect it's not coincidence that I'm the only one still going and I'm also the only one who hasn't had unavoidable missed days from travelling). Alternatively, I'm very good at committing to commitment devices, and they're not.
