Facebook has announced that its eagerly awaited Timeline will roll out today.

The update, which displays posts and pictures chronologically, offers a timeline of your life on the social network, including what you did, when and with whom.

There's a seven-day review period, allowing you to delete unflattering pictures or posts, with the full service scheduled to go live in a week.

However, the Timeline has already caused a stir on Twitter, with Twitter Facebook Timeline trending for many regions.

According to Facebook, they are still ironing out a few bugs in the system, but everything should be ready for the launch.

So, if you're a Facebook user, head over to the network and start looking through your posts. Anything embarrassing or likely to cause a problem needs to be hidden, if not deleted.
