I can relate to this. I know a girl who is super hot in real life. Almost breathtaking but in a few photos I've seen of her she looks average. I also agree with meeting them in person over coffee or something early on before wasting a lot of time Internet dating. If they turn out to be fat or just not what they portrayed themselves as then I would just say, "You misrepresented yourself, bye." Then leave.
My brother went to meet a chick he found on nexus one time and when he got to the parking lot he saw her sitting in her car and she was fat so he just drove off.
I think I might give POF a try I have trouble finding girls that have similar interests to myself. Lots of girls at bars that are nice to take out for a test drive but not too many keepers.
