Oprah Winfrey joined Twitter, the popular online short messaging service, in April, and traffic to the site has grew considerably in the days following "@Oprah". Her first tweet was "HI TWITTERS . THANK YOU FOR A WARM WELCOME. FEELING REALLY 21st CENTURY ." She will help further popularize the tool--extending it into an audience that could help propel the website into the top ranks. Already Twitter is ranked number 38 in America. As the NY Times has recently stated regarding Oprah's "grant[ing] of pop superstardom" to Twitter: "Twittermania has only begun." The true simplicity of the service will only help speed its race to the top.
