Twitter-mood

Here is a cute study that attempts to gauge  our mood (more accurately, the 7% of American who use Twitter) throughout the day.  Play through the video that shows regional and time of day differences.  From the quickie NYTimes mention of the work: "you’re probably happiest in the morning and least satisfied about noon. Analyzing words in those posts, researchers found that Thursday is the saddest day; Sunday, the happiest. People on the West Coast who post are happier than their counterparts on the East Coast. The moods were mapped, showing happy times (greener areas) and unhappy (red areas)."
