Maybe I'm way off but I don't see people paying the kind of money your asking for this. What's the advantage over Yahoo Answers or Quora?

There are girls on those sites as well, there are also plenty of forums for specific questions with male and female members.

How are you verifying gender?

Best of luck either way, what do I know, I thought Twitter would never take off...

As far as constructive criticism:

The site seems fast and functional which is great. I think the logo could be improved and the pink / maroon color and gold / brown text colors could be adjusted.
