Start cleaning your Facebook profile in preparation for this fall. Facebook has said that they will be moving everyone to a Timeline this "fall" much to the dismay of almost the entire user base. For those of you who have managed not to get a Timeline for this long, you won't have much of a choice after this move.
Timeline, originally introduced at Facebook's f8 developer conference last September, breaks away from the traditional and instead puts all content branching off a single trunk, which happens to be a timeline. This has the unfortunate consequence of allowing easier access to your virtual past, allowing content you previously thought deleted to be easily viewed.
Once the time has come for Timeline, Facebook will give you a mere 7 days to review it, and clean it in many cases, before it goes live to all of your friends. Facebook has refused to give a specific time frame for the transition other than "fall." A recent survey shows a large amount of users don't like Timeline with as many as 17% of users actively deleting previous posts.
