Did you notice your Facebook pages slightly different today? Then you are not alone. It seems Facebook has rolled out its new page design today. This changes might take some time to take affect on other Facebook pages.
Previously, Facebook applied its pages design with a three column layout. Now they applied the two column layout design. The right side has the static information of the page and the left side has the post of the pages. As for now, Facebook has not replied about these radical changes.
