I hope you don't think I was putting down your site, or challenging you, or even expecting something more than it is. But the site as it is doesn't show all that it is intended to be, so I hoped you'd have more to say about it.
The questions I asked are important in starting up a new venture: You need to know what your goals are, and how you hope to meet them. Answering those questions can help in making it a reality (and keeping it from fizzling). If there are things you think could be improved over other similar sites, then focusing on those things can help in planning how to do things differently. What would attract the kind of people you want? What would prevent bad behavior or encourage the good? What would help people ask the best possible questions, or give the best possible answers? In planning my own site, for example, my goal was to continue something that had been good, and fix a couple minor flaws; I also had to consider whether other sites met the needs I wanted to meet, making it unnecessary. (None do, but FMH seems to come closest, which is why I'm here too.)
Of course, those questions also could lead you to conclude that helping to improve an existing site would be more productive, or otherwise change your mind. But that's not the intent.
