Woops -- i just posted a response without refreshing the page, which means i missed updates and it came through as logged out. since it looks like there's still some confusion, i'm reposting:

In short: it's not a bug. It's just weird design.

Each Category page has two views: List View (example) and Exhibition View (example). The toggle for these views is on the top-right of the category page (two different icons). By default, it's on Exhibition View, which shows content pages only. List view shows all pages (like User Pages).

You can change the default view by adding __NOCATEGORYEXHIBITION__ to the Category page, as uberfuzzy just demostrated here: http://annoyingorange.wikia.com/index.php?title=Category%3AAdministrators&action=historysubmit&diff=44210&oldid=41892

Yep, i know it's confusing. But now you can tell people how it works.
