I don't think this addresses jkaufman's comment. He asked:

Why aren't these people using the sites that already exist?

These sites already existed when your friends were applying to college. So if they say "I wish this existed when I was applying to college", the key question to answer is why didn't they use any of the competing sites, which did exist when they were applying to college? Your response that "these people looked through your own website's questions" does not address this question.

(As an aside, I would humbly suggest that you read through jkaufman's -- and a few other people's -- advice somewhat more carefully, as your responses indicate that you've misunderstood some of the key points, see also my earlier explanation of a premortem, which had already been explained to you once earlier in the thread.)
