I think HNers seem to be completely unaware that most Facebook users really don't care about user privacy that much.

These "oh crap I have to move my stuff, Facebook owns it" reactions baffle me. I can understand a desire for privacy, but using an online service by definition means you're at risk.

Hosting your own services on your own computers and communicating with open distributed protocols would be the most private way to go, though the problem with that is there's basically no money in building a social media system that works that way, so many attempts (Atompub/Atom, XMPP) have mostly remained niches.
