> With classic chatrooms (or a random vBulletin forums, if you wish) you would meet somebody online, then you would become friends over time and then you meet them in real life. I did that too.

And it was usually themed around a specific hobby or activity, which would naturally turn into offline, real-world activity. almost as if it was a conduit to connecting real people with real interests, who would seek out communities based around their interests, connect, and then eventually go and do those interests.

I was heavily into a few growing up, all of which revolved around real-world activities, which the forum members all actively participated in. One, in particular that really stuck with me for years, was tennis. The forum I was on had monthly meetups for my region (NYC metro area) and dozens of people would show up, engage, and enjoy each other's presence and participation. There was also a travel section, so if I was traveling to another country or part of the US, I'd be easily able to tap into that region's meetup and get a chance to hit some balls whenever I was on the road. Lovely.

What was nice is that genuine communities were formed, and people actually and actively policed their own communities not as a power trip (hey Spez!) but rather in earnest to ensure their communities were welcoming and that whoever was interested in that topic/activity could participate.
