Normally I don't promote sites but this week was different: I was desperate for a topic.
At any rate, meetup.com is actually a pretty cool site, since it allows you to, well, meet up with other people who are interested in the same sort of stuff that you are. That is, face to face, in the real world meetings instead of any of this virtual stuff.
Especially for people like me who are completely introverted and have the social skills of a hibernating grizzly, you can get together with other, introverted people who have no social skills at all.
Like to write? There's a group. Interested in investing? There's another group. Like to play Talisman with special house rules that govern eating pretzels and whether a person chooses craft or physical? Well...I don't know for a fact that a group exists, but if there is, then they probably know about it.
I've tried a few groups and, as with anything else involving random groups of people, you get a mixed bag. It is, however, nice to know that there are other folks out there who are also into the same stuff as you.
