An explosive unbundling predicted

Dave Winer predicts that everything will unbundle. This is an argument that I've been making around the place for the last year. It's inevitable in time:

Eventually, soon I think, we'll see an explosive unbundling of the
services that make up social networks. What was centralized in the form
of Facebook, Linked-in, even YouTube, is going to blow up and
reconstitute itself. How exactly it will happen is something the
historians can argue about 25 years from now. It hasn't happened yet,
but it will, unless the rules of technology evolution have been
repealed (and they haven't, trust me).
