I've joined Tinder and POF!
POF I don't like much. You can see people have checked you out and not messaged. Or you get a message, do the polite thing and reply, and then they assume you're interested!
Tinder seems a lot better! Though the first guy I chatted to seemed great, spent three hours talking the other night, only for him to move on to the sexy talk. Seriously, how off putting!
