Maybe it is time to consider that the promise of 'social media'--that there could be large monolithic services that would function as some kind of pseudo-public space, was just false. Spaces like HN function better because they are more limited in scope, and more community-driven. The needs of community do not easily serve the imperatives of global capitalism. Twitter is not a community space. Facebook is not a community space, no matter how much it might pretend to be. They only exist to bleed you. Looking for a better 'alternative' to Twitter is a false hope. You can't make a community 'scale'.
