He outlines pretty well the costs of maintaining blackboard for college campuses (very expensive) vs. the quality of its product (not so hot).
For some feedback, I think the automatic grading system is interesting but incredibly difficult to pull off. Teachers have a huge, vast array of testing practices and to create a system to easily check them would be very time-consuming. Maybe it'll work for very small cases, like multiple choice.

I think the genius of Facebook is not just the eliteness, but instead a new word I'll makeup called 'localness'. Facebook cordons off the scary, wild web and presents you with people that you know or could at least see yourself knowing or bumping into. Combine that with early entry into the social networking world, very strong and appealing UI, and yes, eliteness, and a few years later, you've got 18 million users.
