Say you're a lonely Howard Dean supporter, a witch, a native speaker of French or a pagan (same thing), a John Kerry supporter, Web logger or Goth, and you want to meet others of your tribe. Meetups is the place to go. Operating by Web and all over the world, Meetups arranges get-togethers in local venues for people seeking their ilk, whatever that may be. Plans are still in flux, for example, for the next Dallas-area meet-up of people who are Elvis. But there are already 53 of him signed up. Hey, even if you're not Elvis, how could you miss? There's a movie in here somewhere.
