Remember back in May when everybody was really concerned about privacy and Facebook? (Ha, ha, I guess that didn't last very long.) And then, remember when people were talking about a Facebook with privacy called Diaspora?

Well, Diaspora launches on September 15th. As they say on their blog:

We are spending a good chunk of time concentrating on building clear, contextual sharing. That means an intuitive way for users to decide, and not notice deciding, what content goes to their coworkers and what goes to their drinking buddies. We know that’s a hard UI problem and we take it seriously.
We aren’t going to stop working after we release. Ilya and Raphael are taking leave from NYU, and we will continue to develop and maintain Diaspora as a long term project. We have shifted our development timeline accordingly, and the first release will be the beginning of something great, not a finished summer project.

I wish them luck, but I suspect that the moment may have passed.
