How do you splinter something that was never cohesive in the first place?<p>Unlike Email, IM, and many other things, social networks have never integrated with anything. (Not that IM did a great job of it, but at least there's more than 1 IM client for a given network.)<p>People should be able to sign on with any social networking provider and be friends with people on any other provider, just like email. There should be open, standardized protocols that allow each network to talk to each other, and route the appropriate information around.
