Initial thoughts are that the homepage's text doesn't immediately show the value add. It mentions being a web app blah blah blah. It should be something like "reviews of schools by real students" or "what real students have to say about dropping 100K on education." I'd probably shoot for featuring a review of school on the homepage, or a teaser view of it. To me - I should be able to understand what it is the site does and why does it benefit me immediately. That's just my $.02
