Honestly, the current state of social media makes me itch. I don't like chasing down "the shiny new toy" just because that's where the people are, especially when the shiny new toy isn't significantly better than the "perfectly good existing toy" I've already got set up and is actually better anyway. (Facebook vs. LiveJournal, I'm looking at you here.) If there are going to be dozens of these sites, like there are dozens of IM programs, then I want an aggregator, just like there's Trillian for chat. The technology already exists — ever heard of RSS for cryin' out loud, you shtoopid websites? The whole point of the web is to be sharing information, not trying to hoard it.
Pfeh. The idea of being an old-guard web grognard hurts my brain.
