This new feature won’t be officially rolled out until after a few weeks, but it is possible to gain early access to it as a developer. Users will be given a one week grace period to go through their timeline and clean up their profile to hide any updates that they don’t want to share with their friends. Since this entirely new timeline view is dependent on past updates, those using the service longer will have a much more complete timeline than those that are new to the service.
Without further ado, lets take a quick look at the Facebook Timeline’s features:
Thisismynext takes a deeper look into Timeline’s three categories- Cover, Stories, and Apps:
Of course, the Timeline doesn’t show everything you’ve ever done on Facebook, but in my brief testing it did a nice job of summarizing my past. For example, when I clicked on 2008 I was presented with the status update from when I got accepted to Penn, updates from when I first started at Engadget, and memorable photos from that year. 2007 was filled with even more photos from a summer trip, event history, and the reminder that I made 208 friends (go me!). I haven’t begun drilling down on a month-by-month basis yet, but it’s sure to get nostalgic.
