Out of all the pages (appx 20) that I manage on Facebook, I only saw it in one and I am sharing it with you.
It resembles little bit like Notes (If you have used it, you know what I mean)
I will update you when I have more info.
Let me know in the comments section if you have seen it in your admin pages.
Follow me on facebook for more updates!
UPDATE: It seems that this is a new 'about us' section but I am still searching for more information regarding this.
