How on earth can you bring up diaspora in this context? Some kind of cruel joke?

I'm downvoting parent and giving you the right link: https://freenetproject.org/

Heh, I probably should have said it's not an endorsement. Just another example of a (dubious) attempt at a distributed social network.

Thanks, it was useful to learn of the project.

Do Freenet now have any social features in it? Last time I looked (few years ago) it didn't have any significant.

It appears to be useful for admins getting convicted of CP trafficking for running a node. Does that count?

Try this one: http://distributedcity.github.com/

The previous incarnation of Distributed City was pretty cool. I haven't looked at their new code.
