Twitter Brings New Communication to the World....Right?

According to this article from Mashable, recent studies are showing that people group themselves on Twitter according to how happy they are. The researchers apparently analyzed words from random tweets and found that certain users had formed "Happy Clubs" where they mainly Tweeted about good things. Everyone else was mainly negative. I'm honestly not that surprised since it's so much easier to be negative on the internet due to at least some basic level of anonymity. Even more of a reason for brands to at least monitor Twitter, to make sure the Legions of Unhappy People aren't negatively impacting the brand!
