I met a girl once in reallife after chatting and phoning with her for quite a while. She was very nice but it simply didn't work out because she was not the type of girl I'm interested in and there were about 500 km between us (and I was 16). We just spent a very nice weekend, with kissing (nothing else), and it was ok. But we lost contact soon (ok, that's my fault, I think, because I'm not good in keeping long-term contacts).
So I think, you _may_ find your love on the net or you don't. As always, there's no guarantee for nothing! You _may_ also meet your love on the entrance of a subway train.
Just to add, there's noone of my friends here who had success dating online, most even tried it. My best friend, though, found two or three girlfriends on the net. But his current and longest-lasting love he found through friends
