Citizen Journalism

I knew about the plane crash on the Hudson 30 minutes before CNN & NYtimes posted it on their website because of Twitter and was able to discover more using their search feature. There's more value than people give credit in this service that increases the ability to share information

Twitter enables search, but does anyone know of a Twitter current events page or application? It seems like there's a continued need to use Twitter to link the little guy to the mainstream. Or maybe Twitter will start making money by selling friends.
