I’ve always been fascinated by infographics, and I’ve really been into research that tries to calculate people’s emotions. This infograph is pretty amazing. It’s taken all the twitters coming out from the US (around 300 million of them), and calculated emotional words people used in their updates to build a map of emotion. Looks like California is the happiest place in the country- but come working hours no one’s happy :-( There’s also video of the map here.
