Oprah joins Twitter, schooled by Shaquille O’Neal

On Friday's episode of "Oprah," the queen of daytime learned all about Twitter with CEO Evan Williams and twitter-obsessed Ashton Kutcher. She set up her account at twitter.com/oprah and even wrote her first "tweet" on-air. Her twitter buddies consist of solely famous people like Ashton, Demi Moore, Jimmy Fallon, Ellen DeGeneres, George Stephanopoulos, Gayle King and the king of Twitter himself, Shaquille O'Neal.
