Mostly from the Internet, sometimes by Conrad Lisco.
A detailed examination of more than 20 million Tweets about the race for president finds that the political discussion on Twitter is measurably different than the one found in the blogosphere-more voluminous, more fluid and even less neutral.
One distinguishing factor about the campaign discourse on Twitter is that it is more intensely opinionated, and less neutral, than in both blogs and news. Tweets contain a smaller percentage of statements about candidates that are simply factual in nature without reflecting positively or negatively on a candidate.
In general, that means the discourse on Twitter about the candidates has also been more negative.
In an experiment that provided participants with an opportunity to buy a discounted coffee mug, those who were told they had been randomly selected to get the discount were 3 times more likely to want to buy than people who believed everyone got the discount. The esearchers say such "special" opportunities may be appealing because people's self-esteem is tied to factors that distinguish them from the crowd.
