Ashton Kutcher and Oprah Winfrey might receive the lion’s share of celebrity-focused Twitter news, but they rank only fourth and sixth, respectively, on Vitrue's Most Social Celebrities list.
The rankings, posted on Vitrue's blog by Reggie Bradford, company CEO, ranks Britney Spears, John Mayer, and Ellen Degeneres as the top three celebrity Twitters, in that order.
Bradford notes that celebrities can use the microblogging service to combat tabloid inaccuracies and interact with fans, but also to effectively recommend products that they endorse because "eight of 10 purchasing decisions are made because of a peer or friend's recommendation."
