Despite my use of facebook I'm against dating sites they are for AFC who can't get laid by any other means. Facebook is also crap but if you know what your doing you can hit a lot of 8,9,10's in a very short space of time.

I have run several experiments over the last few months and can tell you cocky /confident has best success rate.

You look like a bad girl, (a photo with two girls) So who's the naughty one, what's good about you? etc etc

I do however, like your 'Tell me 3 things that would surprise and impress me about you. If you win enough points, I'll message you back' Its a bit canned but it pushes the right buttons
