Facebook recently launched its timeline functionality to the world which the service announced back in September at their yearly F8 event. For a couple of months only developers had the opportunity to explore this new profile functionality, which resulted in millions of users becoming ‘developers’. The timeline shows all your Facebook activity from the moment you started using the service and it even allows you to add events before that. Or as Facebook describes:
Tell your life story with a new kind of profile
All of this in a clean design which allows you to scroll back in time and to which you can add your personal cover image.
