If you thought that Facebook was only for your teenage daughter, guess again. The social networking website had been growing quickly, and, as it expands, has been developing new networks that are aimed at--shall we say--a more mature market.
Photography galleries and groups have been popping up overnight. Photography curators, collectors, dealers and conservators have all found the site to be addicting, with its chat boards, user profiles, status updates, etc.
Because it is relatively easy to set up a profile page and it is free, hundreds of millions (yes, that's right) of users have done just that.
I Photo Central even has a page there. So does Contemporary Works/Vintage Works. Heck, so does the author. Just go to http://www.facebook.com to sign up, and then search for email@example.com , and add me as a friend. Then search for these two groups and be sure to join them.
Besides the three listed above, some of the most interesting photography groups include:
--Photography Collecting, which has a very active discussion board with dozens of topics and hundreds of participants. This is probably the most important of the photography collecting-oriented sites--besides being the broadest in concept. If you have a question on photography collecting that you want answered, this is the place to ask it.
--Vernacular Photography Mafia, which is focused on vernacular photographs.
--Snapshot Mafia (seems like some of the administrators also like one of Facebook's applications so much that they name their group after it). This group is focused on just snapshots.
--Great Photographers of Ours or Any Time.
Plus there are groups for nearly every major photographer (some major names actually have their own regular profiles and some have fan sites) and many galleries.
