Here's a recent twitter story for me: A few weeks ago, I was sitting in my living room, and I heard a bunch of emergency vehicles. I went to the local live 911 site and saw that there was a large heavy rescue response at the interchange between two major highways; 18 vehicles. My wife was searching local news sites; nothing. I went to twitter search, searched for one of the highways, and immediately found someone who was twittering from the scene, and taking photos. That's pretty powerful stuff, but at present, also probably rare. But as more people start to pulse more immediate information into channels like this, along with metadata (as automatic as possible, like location) this dynamic will become more common. And potentially abused.
