Facebook has just announced a new version of its profile called the Timeline at the f8 developer conference. The new layout is meant to be a central location for your stories, apps, and for you to express who you are, utilizing a chronological timeline to highlight the most important content you share on Facebook. Mark Zuckerberg explained it as a way to "share the story of your life on a single page."
The Timeline will allow you to post about "stories," rather than relying completely on chronology for all shared content and Facebook activity. Stories can be starred or hidden, and there are inline privacy controls to control exactly who sees what. Apps will be able to hook into the Timeline as well, sharing things that you like to do on your personal page. Timeline is meant to be completely customizable and mobile-friendly as well. It's available now for Facebook developers, but will be rolling out to users in the next few weeks. In the meantime, read more about it on the Facebook Blog or on Facebook's clever about page for the new timeline..
