Timeline introduced

CEO Mark Zuckerberg kicks off the company's F8 developers' conference today by introducing a revamped profile page called Timeline, as well as changes to Facebook's Open Graph apps platform that make it easier for users to share media.

A Timeline, Zuckerberg says, is "the story of your life," significantly altering the way users' information is shown on Facebook, and presenting "all your stories, all your apps, and a new way to express who you are....It's a way to tell all the important stories from your life on a single page." Shown here is Zuckerberg's own Timeline, including his dog "Beast."
