Twitter says we are angrier on Thursdays

People are angrier on Thursdays than any other day of the week, at least that's what a study that tracked the moods of Twitter users has to say.

The study searched for words linked to certain moods and tracked how frequently they were used on the networking site.

"We''re not really sure exactly why Thursday, but people''s bad moods build from Monday until then," the New York Daily News quoted Northeastern University professor Alan Mislove as saying.

"On Friday, it seems people''s moods change and they become happier until Sunday when the cycle starts over," he added.
