I've said in the past that I'm really nice in person even though I might come across as an a$$ on the Board. The retort was that it was easy to say. Well, that's true.
I don't think we ever know whether or not someone's online persona is the same as their RL personality.
I know that from what I read online, I have developed preferences for some ladies. I don't have an ATF because I never see anyone on a regular basis. But I have developed some "preferences" in who I would like to see based on their online personas.
Unfortunately, I'm rarely able to exercise those preferences b/c travel doesn't take me anywhere near them.
