Facebook is going to change the facebook page Layout from 30 March 2012.
If you have a page on facebook, or you are a admin of facebook page or like any facebook page then you will fill changes in the facebook page.
I am putting here the sample of old and new facebook page look.
Old Facebook Page Layout
Current Following Message is shown by Facebook (for page admin)
"Welcome to Your Page Preview
Review what's on your Page now, and add or hide what you don't want people to see. You can also learn more and see how the new design looks on other Pages like yours.
1. Only your admins can see this preview
2. On March 30, 2012 your Page will automatically get the new design
3. Until you publish your Page, you can see your old design any time"
