Diaspora is a distributed, open source alternative to Facebook that a few NYU graduates want to spend this summer building. They set out to raise $10,000 on Kickstarter, and on the strength of all the backlash against Facebook's privacy problems, the project has raised over $175,000 as of writing. Good for them. There are a LOT of existing projects doing work in this area (like OneSocialWeb, DiSo, Activity Streams), but I'm ok with a new effort working both together and in parallel with existing ones--it increases the chances that something will hit the the target. Interestingly, a Facebook employee recommended to the Diaspora developers that the app exploit Facebook as a platform for third-party apps to host social data but make it accessible on Facebook. Clever. This reminds me of Postel's law: "Be liberal in what you accept, and conservative in what you send." A lot of people have and will leave Facebook, but for now, the majority won't. Any social app that wants success should allow Facebook users to find and interact with its users seamlessly.
