Interesting. Great that theyv'e taken action. Not sure I would drop out of college for this though. However, currently using a blackboard like app, and having spoken to many friends using blackboard, it seems to be pretty crappy. If they can get a couple of schools like Penn to adopt CourseKit, its got some great potential.
Is this idea really worth leaving school for? I know of at least a few competitors in this space, so it seems like a pretty big risk (even with $1M in seed funding) to drop out.
