Here's the great demo video of Facebook's new Timeline feature. The video also captures the maturation of Facebook and its users, who have gone from keeping up with friends to keeping with friends' kids.

Timeline's taking the practice of posting your old yearbook photos to the extreme: It becomes a repository for mementos of your whole life, if you choose to do this on Facebook.

In a few years it's going to have to form a partnership with Legacy.com to extend this to online obituaries.

Timeline's the highlight so far of new Facebook features being announced at the company's F8 conference.

Also announced were new media sharing apps on the Facebook platform, where users can show and share what they're consuming at sites like Hulu, Netflix, Rhapsody and Spotify.
