Facebook’s new Timeline feature is now open to everyone. The service is rolling out worldwide starting today, arriving for everyone across the globe within the next few weeks.

Once you get Timeline, it’s important to note that you have just 7 days to tweak what shows up on it before it’s published on your page. So, if you want to hide that bad relationship from college, or pictures back from when you thought neon was cool – the time is now.

If you’re ready to go ahead and bite the bullet and sign up for Timeline now (there’s no turning back) you can do so by going to Facebook’s Introducing Timeline page. The site has also posted a handy guide for hiding things you don’t want others to see, something that’s definitely worth a look if you were rocking a Facebook account for a while before you friended your boss or parents.

Are any of you already using Timeline? What do you think of it?
