I don't see twitter changing much. They've created a very solid structure that people find intuitive. Facebook is an absolute mess though, and I think they know it. I'm rooting for them to do a radical blank-slate redesign. I'm assuming theres a faction of fb UX people pushing it
In the early days we mostly used Twitter just for goofing. E.g. re: 2009 swine flu outbreak I tweeted:

And then @danielpunkass made this delightful song:

Twitter was better then.
