The color scheme is ugly. I like the gradual change over the name on mouseover but purple to yellow through brown is not the most appealing... That being said the layout is good.
I'm not sure I understand the value. Friends of friends are the easiest people to meet / hookup with already. The purpose of online dating sites is to meet strangers you don't already have an in with. Is there really a problem there that needs solving?
The passive cute / not cute thing sounds interesting. Maybe make that the focus? That's something that isn't already built into Facebook and would definitely solve the problem of some awkwardness.
