Justin Searls quit social media by posting more. How, exactly, did he do that? By writing way too much Ruby code to cross-post his blog to all the social networks using an atom feed of his design. POSSE is an old idea: publish on your own site, syndicate elsewhere. That’s desirable, for sure, but not always easy to accomplish. POSSE Party is the new app Justin released so others can accomplish the same without all the work he went through.
