Study Tracking for udacity.com
You should get in touch with udacity.com and coursera.org to find ways of auto-tracking a person's progress in the courses offered on those sites. Udacity.com in particular seems a good fit, as they have a consistent method of course structure. My first goal is to do daily coursework in courses I'm registered in. Auto-tracking would eliminate manual entry on Beeminder, and would eliminate the temptation to cheat if I make a pledge.

This is an awesome idea. I would be way more likely to complete MOOCs with automatic beeminding.
