A question I find connected: What defines a hacker group?
Presumably in this site's context, what's meant is the nerdy end of web entrepreneurship. There are a number of events here in town which have elements of web, nerd, and entrepreneur, but don't really capture what comes to my mind when I think of a hacker meetup.
I have visited HacDC a few times. Since I don't actually live in DC, I tend to just go when they have events. The people I've met there have always been friendly, and all of their events are open to the public.
They just started getting off the ground last summer, so it's not nearly as fancy as CCC or NYCResistor. Still, they put together some pretty cool stuff. Last time I went, I got to meet Mitch Altman.
Sweet, just added: http://utahcodemasons.blogspot.com/ we are having our first meeting this thursday at borders in provo at 6:30pm if anyone on here is interested. We are thinking something akin to the free hackers union.
HackerSpaces, two in the UK. Hacker Groups, two in the UK. I see PG's essay on moving to where the things you want to be part of are in a different light now compared to when I first read it.
You'll find mostly everybody from last week 25c3 conf there
