Maybe it's a moot point by now, but before facebook was around, there was i2hub and connectU. The rumor was that Mark was a dev for the i2hub/connectu team and he took the idea and made facebook. Because of the RIAA assault of i2hub, connectU died with it, leaving Facebook to take all the fame and glory. I also vaguely remember that this was settled quietly out of court. Regardless, I think it's pretty shady. Maybe it was all just a rumor though.
