The latest major change to Facebook is the new profile look, called the “Timeline.” Being careful about the content you post, and monitoring what others post to your wall, has always been important. The Timeline makes this monitoring process even more important.
On your Timeline, the “Activity Log” is a complete list of your photos and activities you have posted on Facebook. You have the ability to hide content or specify who sees certain items. Going through the Activity Log to tweak what is appearing to others is a good idea, especially for those who are prone to posting pictures they may not want coworkers or potential employers to see.
