Hmm...sounds interesting....dare I risk being thoroughly disappointing?
Don't worry you couldn't possibly be as much of a disappointment as me.
But seriously I have been to many atheist meetings with people I have met on-line and some people just don't match up with your expectations. Some people can be very erudite and sparkly on-line but in real life quite dull ( and visa versa). Mainly because they are good with the written word where they have time to gather their thoughts but aren't as spontaneous in a real-time context. It's almost like you're meeting a different person.
The other big issue can be perceiving somebody as flirty on-line who really isn't in real life. They're happy to flirt in the relative safety and anonymity of cyber space, where body language is invisible, but in real life they just aren't that way inclined. This dichotomy can lead to serious repercussions where there is a serious miss-match of expectations.
I used to consider myself a good judge of character. It turns out I am, in real life, but on-line I have made some real fuck-ups, trusting untrustworthy people and being far too open emotionally to needy people. In the past I used to think I had a lot of good friends on-line when in fact it was only a handful. And some of those 'friends' have turned out to be the most despicable people I have ever come across. But we live and learn.
Never invest more emotion in an on-line relationship than you are prepared to have thrown back in your face with derisive laughter added for good measure.
