I appreciate all of these distributed social networks (Mastodon, Peepeth, Diaspora, etc.) getting some buzz right now. I think distributed hosting of social networks is an important step forward. However, they're all lacking one major thing that needs to happen in order for a true Facebook Exodus to take place - distributed discovery and consumption. Facebook has a HUGE network effect, and simply put there is no way…
That's what POSSE[0] is for: you Publish on your Own Site, Syndicate Elsewhere. So you'd publish on Mastodon & (hopefully automatically) also publish a syndicated feed on Facebook.
