Scientists claim Twitter reveals the mood of the nation

If you believe everything you read, Twitter can pretty much do anything (strangely, it still fails at getting me that date with Eva Mendes). A bunch of nerds in lab coats are now saying Twitter can map the nation’s mood. A team at Northeastern University in Boston is using “a form of ‘sentiment analysis,’ identifying keywords that indicate pleasure or displeasure, to work out how happy or sad” the nation is. Morning is apparently the happiest time of day. — Jackson Wightman
