Awesome.

When evaluating MOOCS, I usually have a list of courses that sound cool, but I haven't investigated yet. Once I investigate them a bit more, I put the good ones on a much shorter list of classes which I actually plan to take.

Features to assist this process of narrowing down potential courses after discovering them (beyond ratings) would help you offer a better product than CourseTalk. Perhaps a calendar or multiple lists (interesting, will take, currently taking, finished -- you get the idea).
