Someone mentioned "HerWay" in another comment. I checked it out, and one unique thing they offer (if you are a male user) is, a limited form of analytics on your profile. Important, because men can't initiate contact.

This had one really important piece of information, that seems counter to what a lot of people are suggesting in these comments: a short initial message is all you need (if the match is good.) He finally settled on a single initiating message “You seem really cool. Want to meet?” and it worked.

I was the one who mentioned HerWay. In fact, men can initiate contact to any woman whose profile they can see. Think about what it would take for a site centered on the idea of taking power from men and giving it to women to make that product move.

The guy basically data-mined OKC and gamed the matching system. Then suddenly the site began working for him, since he looked like The Perfect Match to a sizable number of people.
