When I was at Odeo we did a survey of the office to see who had degrees. I'm pretty sure it was just me and the other middle manager. That's pretty sad, since the fun part of a startup is either being the decider or the doer. Of course both of us went on to start companies, so maybe it doesn't really matter.
Yeah, that's what I want to say. It doesn't matter in a general sense. What does matter, and I've found this to be very true as a founder, is to do things your way. There's no one set of magic advice so you just have to figure out the things that work for you. If school doesn't work for you and startup success is more important than the college social life, then drop out and go for it. If you're more methodical (like me) then graduate, join a startup, learn some lessons, then found your own company.
