Tech and media research firm Interpret surveyed over 9,200 internet users in August 2009 and found that Twitter users are twice as likely to engage with brands—in multiple ways—than other social network users. Roughly 24 percent of the respondents that used Twitter reviewed or rated products online; just 12 percent of people that used other social nets—but not Twitter—said the same. Twitter users were also more likely to visit company profiles (20 percent) than non-Twitter users (11 percent), and twice as likely to click on ads or sponsored links (20 percent vs. 9 percent).
