Today it's a social networking site called Ning. It's seems like the groups found on Yahoo, but it's more public. You don't need a Yahoo account and you can see how big or small a group is. He can see all of the groups at once and preview them. Some of the Yahoo groups I wanted to see wouldn't let me look around without being a member. The site also uses folksonomy to tag it's group, so the search engine can pull in groups that totally related to what you're searching for and what you're NOT searching for. It's also a good way to find local groups (if the location was tagged).
I did look up some groups: artist sites, manga/anime fan sites and composition art journal groups (people who only do visual journaling in those cheap marbled composition books). Some groups had interesting names:
- Many Maniacs Creating Art
- The Land of Lost Luggage Network
- Animation and Illustration Ministry (sounds like a church)
Until then, keep reading.
