If you head to Facebook right now, you may see a new feature on your Wall, sorting. After Facebook recently changed the way information on your Wall was ordered (Top stories / Highlighted stories at top), a large number of users were unhappy. This option for sorting solves that issue and essentially returns your Facebook Wall to it’s previous state.
Recent Stories First: Stories will appear in the order they were posted. Highlighted stories will be marked with a blue corner.
Highlighted Stories First: Highlighted stories you haven’t seen yet will appear at the top of your News Feed. (If you don’t see highlighted stories, it’s because there aren’t any new highlighted stories since your last visit.)
