Timeline comes with a new tool called the Activity Log, which enables you to finely tune what appears on your Timeline; you can “promote” a post to featured status, you can hide it from the Timeline or delete it altogether.
Like all major Facebook redesigns, Timeline was greeted with a fair share of criticism. Some users were concerned about Facebook’s request that users add even more personal info, as well as the fact that Timeline makes this info easily accessible, which could lead to identity theft.
The good news is that Facebook is implementing a seven day grace period, where you can review anything that appears on the timeline and decide whether you want anyone to see it. However, once you upgrade to Timeline, that new profile will “go live” at the end of the seven-day review period.
As of today, Timeline will also be available on Android devices as well as the mobile version of Facebook – m.facebook.com.
