http://www.needthebook.com/<p>The idea is to use peer reviews to find out if you really need to buy the textbook(s) for a particular college class. (I've had a few classes in which I never used the textbook at all, and I suspect most others have too.)<p>I would appreciate your opinions about the site's functionality and the idea's feasibility.<p>There is clearly a "chicken or the egg" problem, which I am struggling with.  Most visitors do a quick search for one of their classes, see that there aren't any reviews yet, and immediately leave.  Suggestions for incentivizing the review process would be excellent.
