[ via Scott Loftesness ] Frank Booseman would like blog tools to support walled garden posting. He’s inspired when a friend would love to post photos from a party, but not to the whole world. Live Journal, which I’ve been playing with lately, supports this. It can, because it’s a monolitic (on the server-side) application. I created a LJ account, and friends who were already there added me to their ‘friends’ list, and added them to mine. They post a private entry, and their friends see it, but not others. As one longtime friend from Fandom pointed out, this means you have have online exchanges which are more like the APA’s we were in during the 1980’s and 1990’s.
Using FOaF, authentication, and some modules bolted onto RSS, that would be a start.
