The following are screen shots from a live QlikView application we ran during the AnDevCon III Conference May 14th - 17th 2012 which tracked all Tweets containing the hashtag #andevcon.

The application also scored these Tweets for sentiment, extracted keywords and looked up the Klout score for all the Tweeters. You can see the data model for the application at the bottom of the page.
