Conan O'Brien's Twitter Buddy Shows Class Sarah Killen is doing more than just cashing in on fame By John Johnson, Newser Staff Posted Mar 9, 2010 4:28 PM CST 12 comments Comments Sarah Killen, in a screen grab from YouTube. (youtube.com) (Newser) – When Conan O'Brien picked Sarah Killen at random to be the person he'd follow on Twitter, it wouldn't have been a huge surprise if she milked her fame and turned "into a real douche," writes Mary Elizabeth Williams. And while Killen has indeed become a bit of a media darling and even raked in a new iMac and other pieces of swag, she's also used her celebrity to raise money for breast cancer and help a charity that feeds children. "Sure, there's a pleasure in the fame of it all for her, too," writes Williams at Salon. "But there's something lovely and breathtakingly generous about someone with newfound notoriety leveraging into something other than just more notoriety." She may have been picked at random, but Killen was an "inspired choice."
