I personally don't. I like to listen to the 'This Week in Tech' podcast, and those guys are obsessed with Twitter. I groan loudly every time the conversation comes back to Twitter which is like every ten minutes or so. It has almost become unbearable. Between that and TechChrunch, I've entered backlash-mode on the service, and I have never even used it.
