Our Collective Mood—According to Our Tweets

This is kind of cool: A team of researchers have created a video that shows a 24-hour mood cycle of the country based on our public tweets.
Before you watch, Sune Lehmann, who studies complex networks, explains how to read the mood map:

Green corresponds to a happy mood and red corresponds to a grumpier state of mind. The area of each state is scaled according to the number of tweets originating in that state. Note how the East Coast is consistently 3 hours ahead of the West Coast, so when we’re sleeping in Boston, the Californians are tweeting away. It’s also interesting that better weather seems to make you happier (or rather, that better weather is correlated with happier tweets): Florida and California seems to be consistently in a better mood than the remaining US. Also note how New Mexico and Delaware behave very differently from their neighbors.

Lehmann and his colleagues also found a few other interesting trends. We seem to be happiest on Sunday mornings and the least happy on Thursday evenings, and we’re happier on weekends than during the week (no surprise there). Our happiest times of day are early morning and late evening, and people on the West Coast appear to be significantly happier than people on the East Coast.
