Diaspora*, the open source social network released
their source code yesterday.
Their goal is to create a social network where you control your data and your privacy.
The code is in Ruby, a language I don't speak but I intend to learn it just so I can work on this
project. Imagine if you had the code to Facebook and the ability to change it, that's what Diaspora
represents. It also makes it easy to host your data anywhere, even a personal server.
It's licensed under the AGPL.
Fun :)
EDIT: Here's the
release announcement and some previews
