When actor Ashton Kutcher and CNN were racing last month to see who could amass 1 million followers first on Twitter, many people tracked the race at Twitterholic.com, a site started as a joke by two Florida Web developers. Alex Rudloff of Satellite Beach and Gavin Hall of Orlando built the site in a couple of hours back in early 2007, when Twitter was new and the only people using it were the tech-savvy set. The two University of Central Florida graduates thought it would be funny to quantify just how addicted people were to the micro-blogging site.
