If you're one of the few who has yet to be upgraded to Facebook's Timeline view, you'll be forced to make the change by the end of this year, the social network has confirmed. Users who still have the previous design will be notified of the change sometime before the end of this fall, at which point they'll have a week to curate and publish their Timeline before it automatically goes live. According to TechCrunch, the decision is due to Facebook's recently launched mosaic photo view, which incorporates Timeline functionality. Facebook has slowly been rolling out Timeline to users since the feature launched in late 2011, and earlier this year added support for Pages as well as users.
