When we connect on a new social network like this we're really just re-forming the same networks we've already formed. Things that don't already have hashtags still don't exist. For instance there doesn't seem to be any community following any tags about non-sexual affectionate touch, #affectionatetouch doesn't work, nobody searches for that. People tag #freehugs when they do that meme-- but nobody goes back and discusses the concept. So, there's no spark to start a new network's same fire from.
