Obwikipedia: Subcategories really, really don't work. Why have we put up with them for so long? I was trying to categorise [[Brownstone]]. First I chose [[Category:building materials]].

Because there you end up in a category with 3 other members, none of which were real building materials. I ended up using both Masonry and Stone, violating the rule against using a cat and its subcat together.
A bit of rearranging on the categories helps. I might look at this one later, but I am trying to fight off a proposal to have Category:German beer and breweries etc. Some people dont understand how to parent categories.
To do it well you need to look at the category system in a whole subject area. It requires a lot of editing to fix. But its worth it when its right.
I don't supposed you've seen the wonders that can be achieved with http://tools.wikimedia.de/~daniel/WikiSense/CategoryIntersect.php by any chance?
