Kudos and the expert tab

I was just wondering, when one clicks on a kudos button that has been used it takes you to a page that shows who had pushed the kudos button under the All Users tab. However I have not been able to find what exactely the Experts tab is for in that same window.  I thought perhaps it was to list Symantec Employees that had kudoed the post but that does not seem to be the case.

 

Take care,
