That's exactly what I was doing with my edit (I deleted all the duplicate categories (accidentally?) added by the previous edit), so I'm not sure what you're getting at here. Incidentally, I have opted-out of the Achievements system (a global profile setting; in my experience, achievements are worthless as, although they are supposed to encourage editing, in practice they mostly encourage trivial or vandal editing) hence have no reason to be making pointless edits.

And I agree that categories generally can be overdone; on Coasterpedia, there was even a "Coasterpedia" category (since removed with the help of AutoWikiBrowser)! Since the purpose of categories is to help users find pages they might be interested in, I for one see no point in categories which could only ever contain one or two pages, or which (as the in example I just gave) cover every page on the wiki, or almost every page. How does either of those types of category serve any useful purpose?
