There's Friendica & Diaspora, but the problem is how I use Facebook. For me, it's a people repository, because everyone is there. If I haven't seen someone in a long time but need to contact them I'll log in and message them. Do I need to cyber stalk them to find out if they're a crazy person? Facebook. Planning events that include strangers? Facebook.

Unless an alternative reaches even higher critical mass than Mastodon, it is essentially useless to me. I don't actually need or want to post statuses and pictures.
