I just activated the new Facebook profile and timeline, and honestly it is pretty damn cool. Especially the timeline. It basically turns your Facebook life into a sort of digital scrapbook that you can browse by year. I am going to watch the F8 Keynote and learn about the other features, but the new profile will definitely going to shake things up a bit. But I see Facebook as a service becoming more useful to people long term with this timeline feature because people love their memories.
