It seems to be fast enough, and not too difficult to figure out. I don't think it's intuitive enough, though. A login with Facebook (or Twitter), I think, is becoming crucial. Also, a new way of thinking about ToDo lists, would make it a little more appealing, such as a 4 quadrant list based on a vertical scale of importance and a horizontal scale of urgency: http://www.mindtools.com/pages/article/newHTE_91.htm

Also, I think if this was tied into something people are already using, such as Evernote, you'd see more usage potential.

They just need to add more courses now...

can you start with some dumb-downed obvious places, and slowly work up to harder and harder to recognize? Even something as simple as Statue of Liberty or Mt. Rushmore would be a good introductory... IMO

Seems a little thin and scattered. There's a ton of amazing (and free) info available from Stanford.

great idea! but, I think you could be well traveled and not know a single one.
