"Social" should be an Internet protocol. The only reason it's not is that we basically stopped making protocols (well, ones that gain any meaningful traction, anyway—I'm aware there are some lightly-used efforts at social protocols) because all the companies in a position to push them to a meaningful number of users are better served by making interoperability difficult. The "free" services spyvertising economy, where captive non-paying user count & eyeball time is what matters, is why things are this way.
