This in short is a great piece of design. Especially coming out of facebook this is amazing (well they now have one of the most talented designers so not that surprising). However, as a business this is killer and shrewd. Everyone would want to save a log of their life. More app permissions to add to timeline > more auto posts in ticker > more connection for Facebook.

How cool is this going to be for kids who grew up with Facebook and their kids and their kids' kids? I would love to have had insight to this level of detail for my ancestors.
The one condition I have, though, is that I don't share it with anyone except someone I explicitly want to share it with. With everything being absolutely private and in my control to carry with me, by default, it would be killer. But this could well be opposite to Facebook's own direction.
All-in-all, this is a rehash of the news feed with a few more controls. But the presentation is really nice.
