August 23: You Will Lose 30% of Your Marketing Space on Facebook

Facebook previously announced that they would be reducing the width of custom application tabs on Pages and removing the popular Boxes feature. Last week, they posted the following announcement:

Based on feedback from developers, we have committed to the following plans to ensure a smooth transition:

• Boxes. We will notify users via messaging in profile boxes and in the Help Center that the "Boxes" tab, boxes on profiles and Pages, and application info sections will be going away.
• Application Tabs. Next week, we will give Page admins the ability to preview their custom tabs in the new 520 pixel width so they can modify their layouts as needed. All profile and Page tabs will be resized automatically beginning the week of August 23.

They had originally said the early part of 2010, but that has since passed. If you are using the Boxes feature or have a fixed-width Static FBML tab, you will need to replace those features before August 23.

So congratulations! You just lost 30% of your marketing space!
