Devil's advocate checking in...<p>> Greeks have specific needs that Facebook and other sites do not meet.<p>Such as?<p>> At UPenn, the average budget is ~$125,000 a semester, and that's money each house MUST spend.<p>Perhaps, but what fraction of that do they spend on software, social networking or otherwise? A frat budget of $125K becomes less interesting if they spent $110K of that on Natty Light.<p>> CollegeACB had 900,000 hits its 2nd day, now its down.<p>I'm too old to have experienced it directly in school (thank God), but from what I can tell CollegeACB was basically an anonymous message board that got canned when the discussions (predictably, given the "anonymous" part) took a turn for the offensive. Another previous site that did the same thing, JuicyCampus, also failed in much the same way.<p>But neither of those sound like reasonable comparators to what you're talking about anyway, since (1) they were both targeted towards students in general rather than just towards Greeks, and (2) they were free, whereas you're talking about charging. So it's kind of a lose-lose comparison; if your product is like CollegeACB and JuicyCampus, it's likely to commit suicide via user-generated douchebaggery; if it ISN'T like them, those 900,000 hits don't really speak to the existence of a market for what you're selling.
