Just out of curiosity I have always wondered which items make up the 30 items in the server ranking. I assume that for now this list is static and does not change.
If that is so, I think it might be informational for some of us who delve in Economics, or just like to scour over information, to highlight those items which make up the server ranking.
Like the NYSE, certain companies will have a note next to their name - "Makes up part of the Dow Jones Industrial Average"
My idea is to possibly mark these items with an asterisk or colored box (only on the item's single page?).
-Here is a rough example I made really quick with photoshop
You could then also have a link showing all the items and their current prices for each server, under each server's link.
