Facebook users have only four days to scour through their pages and delete any embarrassing status updates, photos or videos. The popular social networking site is in a hurry to make sure everyone uses its new Timeline infrastructure, so it has decided to switch it from being a nice option to a mandatory feature. Facebook users will be switched to the new-look Timeline on Feb. 1 which will expose their entire history on the social-networking site for the world to see. A post on the official Facebook blog Tuesday declared: “Last year we introduced Timeline, a new kind of profile that lets you highlight the photos, posts and life events that help you tell your story. Over the next few weeks, everyone will get Timeline. When you get Timeline, you'll have seven days to preview what's there now. This gives you a chance to add or hide whatever you want before anyone else sees it.” Timeline is the shiny new magazine-style tiled layout that creates a more visual look to your Facebook wall as opposed to the linear text-driven style users have learned to live with over the last few years. The Timeline feature includes a slider that lets users delve all the way back through someone's history on Facebook. The move ties in with Facebook's recent launch of more than 60 apps geared to work with Timeline, from cooking to sports, music and fashion. Facebook founder Mark Zuckerberg unveiled the Timeline profiles last year, saying the social network wanted to allow its hundreds of millions of users to create an “online scrapbook” of their time on the site. Facebook is the virtual home to more than eight hundred million active users. Saudi Arabia is the second-largest Arab population on the largest social networking hub with over two million Facebook users as of April 2010. More than half of Facebook users in Saudi Arabia are between 19-29 years of age, while 25 percent are between 30-45 years old. Males dominate Facebook in the Kingdom.
