This is a fairly neat idea on the BBc Radio1 website. The radio station gets a lot of text messages between 500 and 1000 an hour, now you can see a tag cloud of common words from the messages. It would be cool to see some of dynamism evolution of words as they grow more popular but all in all a cool concept for the BBC.
