A fantastic use of tag clouds & example of new forms journalism can take

You use the slider bar at the bottom of the image of Mt. Rushmore on this site and you can see each of our American President's State of the Union Speech summarized as a "tag cloud." Just stop for two minutes and consider the number of story ideas that you come up with based on this unique view of American political, economic and social history. Linguists could have a field day with this. What geeky fun!

Oh, just in case YOU can think of a phenomenon which is calling out for a tag cloud.
