Dating sites are simply horrible at actually creating awesome interaction, and one of the first reason is the fact that obviously looks are pretty much irrelevant for that, yet most seem centered on photos.
The site is empty for me other than the top bar though, so can't give any more advice for it.
IMHO the most important thing though is to match people that want the same thing out of dating.
I.e. if someone wants to have a one night stand and the other wants a long monogamous relationship they should not even see each other's profile, yet pretty much all dating sites don't even let you state your goals!
