I don't understand the "blow away all their user accounts when they get bored" statement. I'm guessing I'm missing something in Diaspora's history?

Diaspora has always been a joke, ever since that first awful naive release.

It's a good idea (and older than the diaspora project) and kudos to them for pushing forward, but I really hope someone else implements this idea correctly.

Maybe they're just encouraging you to run your own server.
