Open Source Everything Except For Facebook/MySpace

There are open source Diggs, Wikipedia (technically the foundation is open source, but you know what I mean), ECommerce, Forums,Photo sites, etc. Why has no one organized an open source version of facebook/ myspace that is clean, nice, and allow plugins? Seriously, this could be huge. Just a random idea that I’m throwing out there, that will hopefully jump start it. I love open source software. Contact me if you’re working on this or have some ideas. This way anyone could add a social network or community to their site.

Update: I know about PeopleAggregator, but it isn’t what I’m talking about exactly.
