From today’s New York Times:

Twitter has been described many ways. At its best, it has been called a revolutionary political tool and a low-cost marketing machine. At its worst, it has been dubbed a waste of time.

Now, two researchers are calling it a hedonimeter, a device that measures happiness.

Peter Sheridan Dodds and Christopher M. Danforth, a pair of statisticians from the University of Vermont, are hoping to harness the stream of messages flowing through the popular micro-blogging platform at any given moment to read public opinion and sentiment in real-time.

Sounds a bit similar in concept to a piece I wrote two years ago.

Yes, the application was an April Fools’ joke, but the concept isn’t.
