[ WoWWiki ] = "This article is about . . . WoWWiki.". The Article Type identifies the type of article the reader is looking at. It is used to clearly distinguish between commonly repeated TYPES (CLASSES) OF ARTICLES without necessarily turning it into a Category list. (An article type CAN be a Category:, but it doesn't NEED to be.) The primary purpose is to quickly (“at a glance�?) identify for the reader what the article is about -- for this reason, it appears at the top of the page (as opposed to Categories, which appear at the bottom of the page.)
