Well, in my experience, and I'm a huge geek, in both senses of the phrase, that I'm a big lardy git as well as a gamer, and I've found more sucess in online interaction leading to real world meetings, over inciting a social link in the real world first.
Reading back, its quite obvious why, too.
This links to another forum thread about why men don't pick up on the subtle signs given out by women, too.
Essentially, I believe I have a fair bit to offer, but zero confidence about my physical image, however, if someone enjoys my company online, I'm open to meeting IRL as I know I've already 'sold' them on me, and that I may get past the initial 'first impressions' of looks.
Strangely enough, I've never really sensed any disappointment in a first meet either, but of course that is not going to eradicate the belief that most women would run screaming from the idea of spending any time in my company.
