New new media

Re: those data visualizations of tweets during the inauguration, and tweets around the continent during the Super Bowl:
It's a whole new model for what we consider "news."

My idea for a new news-delivery medium: a map superimposed with tag clouds following blogs, tweets, newspaper stories, etc. -- maybe even whatever combination of those each user is interested in. As in Google Earth, you could zoom in anywhere in the world and get impressions of what people are talking/writing about at any given moment.
