Lucky 10000?
Three tricks if you didn't already know:
1: you'll find categories at the bottom of regular mediawiki pages
2: if you click one, you'll end up on a page like eg. this: https://en.wikipedia.org/wiki/Category:Computers
3: the tree style tabs plugin in combination with middle-click is criminally underrated for navigating hierarchical data. (middleclick open-in-new-tab is only mildly handy, tree style tabs seems tepid by itself without it)
TIL, I think I've landed on these pages a decent number of times but never from wikipedia's internal nav. I assumed they were more of an adhoc occasional thing, not a standard for sorting all pages.
