The promise of Diaspora was that your "facebook" was a server that you controlled which allowed you to link up with everyone else.
Google is dumb. Google is dumbly dumb. Their move wasn't Google Plus, their move was to sell rack space and Diaspora instances that you subscribe to through your Gmail which you configure and you keep running and you manage and you link up. Make them a dollar a month. Fuck advertising. Allow people to expand or shrink CPU usage for things like protein folding or aircraft search or decrypting the Voynich Manuscript or WTFever. The fact that a company that buys servers like they're cord wood decided that the way to beat Facebook at their own game was to suck at it says everything you need to know about why fucking Section 230 needs to die. If people roll their own iron they're immune forever and if someone is running their "business" in a way that crosses the feds, the lines are a lot more easily crossed.
