Twitter has become more popular than LinkedIn among social network users in the United States. More than half of social network users have associated their profiles with a brand, company or product, and social network users are more likely to say positive things about brands, companies or products. This Anderson Analytics study tracked U.S. user behavior for 11 months. In May, the firm surveyed 5,000 users, and then conducted a 15-minute survey of more than 1,000 users and 250 non-users, age 13 and older. Lots of stats about Twitter, MySpace, LinkedIn and Facebook Users, including demographic details, at MediaPost.
