During the earlyish (pre-teen I suppose to anthropomorphosise) days of the WWW ('93) I used to spent a lot of time on the online real-time 'talkers' based on the Ew-too code. Called Foothills, Surfers and a myriad of others, but those were the two I hung around on. Foothills was US based, Surfers UK. Anyway, it was really cool as I got to talk to actual people around the world!
So there were a couple of meets organised, and as Reading University had a fairly large Surfers presence, the first meet was held there. I think around 30 people made it down/up/across. That was pretty weird, as you may imagine it was mostly geeky types that turned up. I found it all very uncomfortable in the main, trying to get along with people IRL when previously it was so easy to do so in text form. There was a lot of posturing and geeky showing off. Not much fun.
Now I'm a bit older, I can appreciate meeting folk from the internet - it's a lot more common now, so people have got used to doing it and 'know' how to behave. If you follow.
