FWIW, when Facebook went big in 2005 as it started spreading across schools, CMS'es PHPNuke, Mambo, Xoops, Drupal, Joomla, Post Nuke and many more had been around for years. They were and are called CMS'es first, but really they are social networks too. I was customizing Xoops in 2003 and there were a lot of modules to choose, which could have easily done exactly what FB was doing at the time. FB packaged it up nicely and broke into the cool people first.
