I know there's a fair amount of overlap between Wikimedians and folks experimenting in the Open Microblogging world... There's going to be a meetup of Identica 'denters here in SF, 7pm this Tuesday at the Edinburgh Castle pub on Geary:

Anybody want to come hang out? Evan Prodromou will be in town, doing a little post-RecentChangesCamp traveling down the coast. Come hang out with wacky microblog & wiki people! It'll be fun!
