Thousands, and no decent way of separating the wheat from the chaff. Their filtering options suck. I'm also a bit disappointed that (most? all?) of their courses don't feature interactive exercises the way Khan Academy does. I mean I get they started out as basically a repository of recorded lectures, but i.e. a Linear Algebra course is pointless without practicing problems. A few overly simplistic multiple choice questions are the "best" I've seen on on Coursera.

Mean while their prices seem to go up every year.
