Microjournalism?

Journalists are increasingly finding new ways to use Twitter. The microblogging application is now used by some online journalists in the American campaign trail. Cyberjournalist.net points out John Dickerson, who worked for years at Time magazine, and has moved from print to online articles to blog entries to text messages no longer than 140 characters, or about two sentences. “One of the things we are supposed to do as journalists is take people where they can’t go,” he said in an interview for the New York Times. “It is much more authentic, because it really is from inside the room.” Is "microjournalism" another example of convergent journalism and maybe a future form of providing breaking news?
