What’s your mood?  Twitter used for a national happy scale

Happy?  Angry?  Mad?  Twitter knows it, if you buy into the research.  Learn more about how the nation’s mood is being tracked on Twitter.

Researchers from Northwestern and Harvard are behind the project, analyzing the words you tweet that float through the Twitterverse.
