Los Angeles Times :: Several hours before a semifinal race this week, Michael Phelps alerted his fans that he planned to take a nap. At roughly the same time, across town, basketball star LeBron James was visiting a sneaker shop. And, apparently, Jamaican sprinter Usain Bolt needed a shave. "Just posted a photo," he said. It seems that every moment of the 2012 London Olympics so far has been documented — 140 characters at a time — on Twitter. The popular microblogging service has become more than just a forum for athletes and fans to share their thoughts. It is a part of the story at these Games.
