Appleseed Project is Back!
Appleseed Project, the coolest social networking site I’ve seen, has just released a major update to its open source code.
Appleseed servers can federate with each other, like an email server or Jabber IM server, so that you can run your own. Users on one can befriend and interact users on others. This works around the bottleneck existing sites run into, with 100 million users trying to work off one cluster. Scalability like that is hard, and site downtown affects every user. The email model is more robust, and it is a natural fit for open source social networking.
Download the code from Sourceforge, set up your own server, and help out!
