Yea. I suspect power users won't exist with this app. School reviews just won't work like a product review site or something. You may buy and review several things a year. But you'll only ever go to 1-3 schools and only a few of them will ever make a review. But if you can rank, lots will read them. Your job (probably) is to cause the former to create reviews by any means necessary (Maybe talk to school admissions folks at different universities and work out a deal of some sort.) and create a business model around the traffic from of latter.
