In mid-March Facebook announced that it would be updating its Timeline design with a focus on users' interests and app activities. Now the the new "Sections" are finished rolling out and you should be able to find them in the left-side of your profile. Now users can rate books, shows and movies in addition to curate personal content from other apps. As a bonus to developers that are integrating their services (such as Goodreads, Spotify and Endomodo), Facebook is offering a new App Insights tool to track user engagement through the Sections section of people's profiles. So head on over to your profile right now to get a tweaking -- you probably don't want people to see how much you love that Bruno Mars album.
