Adam - in my experience women very rarely approach first men online, for the main reason being they do spend a lot of time fighting off the "asl, u sound hot" crowd. I don't think it's as bad on message boards as it is in chat rooms, but I don't want to even think about what kind of replies some women must get to adds on a personal site.
It's not like I can blame them for getting scared off. Some men are, indeed, pigs.
I know that if I have been approached, it's been on the grounds of friendship, and I always try and approach others the same way. Is it the longer, perhaps even harder path? Perhaps, but I've found it to be the far more fulfilling. You'll find someone in time if you're the kind of guy you seem like (meaning honest, capable of carying a conversation etc), and then you'll have a good reminder of that old addage, quality over quantity.I wouldn't go altering your profile too much. In my view, just be honest about whatever you have to say in it, go with your own truths, and let that be the crutch you use to stand on. One can do far worse as a starting point.
