Facebook.com â?? a company that less than a year ago looked like fools for not accepting Yahooâ??s bid to purchase it â?? has become the powerhouse of social media websites. Itâ??s been said that much of the success is due simply to Facebook being the latest in a string of recently-hip online socialization sites, with MySpace being the last destination to peek out and then slow as the â??true hipstersâ?? move on, drawing the semi-hip behind them. A large part of that rise, however, has been Facebookâ??s open source policy with regard to the creation of Facebook applications. The result has been twofold: A huge demand for fun and informative applications and the corresponding, explosive proliferation of applications created for the site.
