The National Mood map on Twitter

Feeling Moody? How the time of the day,the day of the week and your geolocation affects your mood/

Researchers analyzed over 300 million tweets collected between September 2006 and August 2009 to determine the mood of America over a 24-hour, 7-day period, and by geolocation. The mood of each tweet was inferred via Affective Norms for English Words, a word-rating system that gives normative emotional ratings for English language words.
