That Udacity is behind this initiative makes this much, much more exciting to me (I'm not big on the whole MOOC business, but Udacity is different; it's the Khan Academy of MOOCs). I've found them to hold themselves to a very high standard, and as someone who's been right in the middle of education-based experiments gone wrong, this makes me feel a lot more optimistic about this project.

Still, I'd recommend people at least let it run for a full one or two years before giving it a shot. The second mouse gets the cheese and all that.
