Many people undoubtedly saw the excellent previous post by Pharos, about the benefit of big discussion tables at Wikimeetups. This is one of what I hope to be many posts about on-the-ground wiki activism.
The USA currently does not have a chapter like so many other countries do. There have been some other attempts in the past to create such a chapter, but none of those attempts have reached the necessary critical momentum. There have been some efforts to create state-based chapters as well. This is easier in many respects, I think, because when you're local you can get together offline and build up enthusiasm in a real way. There was one such effort in PA to create a chapter, although that is currently dormant. There is also a very impressive effort happening in New York, and we've all heard a lot about their efforts.
I've also heard some very encouraging things from other people as well, especially from some of my newly-created contacts in Oregon. In Portland, several wikimedians have been participating in a "WikiWednesday", a monthly informal meetup.
Pharos, one of the prime movers in the NY group, came to me with the suggestion of expanding my PA blog to cover the NY volunteers and others from the region. So, I turned this little blog into a group blog that people can use to talk about wiki activism from the Northeast region in the USA. If other people are interested in joining this blog and trying to build up some enthusiasm, leave us a comment about who you are and what you are doing. I'm not going to strictly define "northeast", so consider the boundaries to be extremely fuzzy.
