If you thought yesterday's Facebook changes were dramatic, you'd
better sit down before you see what's coming next. Today at F8,
Mark Zuckerberg led off by showing off Timeline: it's the future
of Facebook, and it's a tectonic shift.   Zuck calls the new
Timeline "all the stories, all your apps, a new way to express
who you are." The story of your life. Your entire Facebook life
has been condensed into a wider one-page destination. Taking a

new splash photo on your profile page. The large photo does not
replace your profile pic. Zuck says it's a way to express who
you are. All content is in your Timeline view now, including
apps.  As you move down your Timeline, it condenses your story
