Hey Dan, Thanks for the feedback. We're aware that many universities already use software like Blackboard and Moodle. They are, however, a pain to use. The systems are also disconnected from the student's normal activities. If you're friends with students on Facebook you'll see that they often try to collaborate using their own status updates. So to answer your question: students would do this on Facebook because they already are. It's not that our service does anything better or more efficiently (though I believe it does) --- but we're deployed on platforms that give us tremendous leverage (Facebook, iPhone (coming), etc.).
