"The story of your life."
With that phrase, Facebook CEO Mark Zuckerberg introduced the company's new Timeline profile in the fall of 2011. The social network's original profile page, he explained, was the first place where most people "felt safe expressing their real self" on the internet, but it was only the "first five minutes of your conversation." A major redesign in 2008 extended that to "the next 15 minutes." Timeline, though, was the "next few hours." Your true self, in full.
To illustrate the point, Zuckerberg went on to show a promotional video that put This Is Your Life to shame by recapping one man's life from his own birth to the birth of his child (and then some) in just over a minute. Facebook has always wanted to be your online identity -- your internet, in many ways -- but it was now also bringing something else to the fore that once had a tendency to fade into the background; your memories.
