Distributed social networking is a hard problem

Well, all these communications systems (usenet, email, facebook) sort of do both 'flooding' for _public_ posts, as well as 'less than flooding' with posts that are made directed at a subset of the public. Of course all of this depends on being able to run/host servers against an internet connection that respects the 'Right To Serve'[1]. But there I go with my own social network flooding techniques... :)
