User blog:Kwitbeck/Cleaning up categories?

As you know, lots of users limit their participation to adding categories to pages. Most of them are red-linked and so do not go back to a category page. Wondering what people thought about these ideas for cleaning up? Let me know what you think in the comments!
 * 1) User page that defines acceptable category criteria. For example, it can't be redundant of other categories (e.g., "screamers" vs. "children who scream bloody murder"), insulting/profane, and supports organization of the wiki.
 * 2) Creating category pages for "approved" categories (and protecting them so they don't get deleted). This would require going through all pages and deleting ones we don't need or want. Then when people add categories that have no category page, we can just delete them. It wouldn't require any real thought to clean it up because they'd be red.
 * 3) Regularly review Unused Categories at http://supernanny.wikia.com/wiki/Special:UnusedCategories and Category Tree at http://supernanny.wikia.com/wiki/Special:CategoryTree (once we have established a standard list of base categories).
