The idea of having your entire history presented for all to see is scary! This is why I barely use my FB page.
Yep, if you are on Facebook, you already have your entire history presented for all to see. The
Timeline feature just makes it easier and quicker for people to navigate while presenting it in a visually appealing way. Also, you can choose which posts you want featured in your Timeline or hide them altogether; better options than the way it currently is.
I normally really hate Facebook, but for me it is a necessary evil; hate the way they constantly change little things for [seemingly] no reason, but I have to admit, I am really liking this Timeline feature. From a designer's point of view, it just looks really nice. If you have a developer's account, you can activate it now. Below is a screenshot from my own Facebook wall/timeline if you haven't seen what the layout looks like yet.
I really think this may change the way people interact with Facebook in general and make it a much more enjoyable experience (hopefully!)
