WordPress meetups
There are WordPress meetups organized round United States (they ask you for your zipcode). This site is run on Movable Type, but my other project is hardcore-WordPress (I think I went live with 0.98), and I’ve been just lazy enough to migrate the entire thing to WordPress (oh, that, and the fact that it doesn’t support multiple blogs off a single install yet).
1.3 promises a bunch of different features, none of which I find specifically useful (I always wanted an integrated RSS reader, and the ones I’ve written are all Perl-based, and the one here is an MT plugin), but the ones that are coming up look promising.
