Facebook CEO Mark Zuckerberg announced a bevy of features to be baked into its social network soon, including one called Timeline that allows you to chronologically chart your entire life via pictures, Facebook updates, Likes, and places you've traveled to and lived. The new features are being announced Thursday at Facebook's f8 developers conference. (Conference keynote is in progress.)

Another big Facebook addition will be supercharging its Open Graph technology that Zuckerberg says will allow you to share everything on your Facebook profile and Timeline from game activity, music, movies, and what you read online.

Users will be able to add information to their timelines (for example, uploading photos from before Facebook existed) and decide what information is visible to the public, to friends, and to other Facebook users.

"Millions and millions of people have spent years curating the stories of their lives, and today there's just no good way to share them," Zuckerberg said. "We think this is a real problem, and we think that we have the solution."

Comedian Andy Samberg helped kicked off Zuckerberg's keynote with a standup routine where he pretended to be Zuckerberg and introduced fake new features including one called Slow Poke--a Poke that takes 24 hours to reach its destination, thus allowing you cancel the Poke in the event you were inebriated or have regrets, Samberg says.
