After being greeted with mixed reactions, millions of users have warmed up to Facebook’s new layout, dubbed Timeline. The new face of Facebook places all of a user’s interactions with the social network on the profile page in reverse chronological order, giving friends a single destination with infinite scrolling on which they can observe all status updates, photos, wall posts and more. While Facebook tried its best to make the transition an easy one, the company said in January that the slow march to making Timeline a requirement was underway. As of Friday, Timeline is no longer an option and those users who have not already made the switch will be forced to do so.

UPDATE: A Facebook spokesperson contacted BGR to clarify that only Pages are being updated today. Timeline for profile pages are still being rolled out and there is no concrete date for when the mandatory changeover will take place.
