Wikidweb:Category Intersections

From Wikidweb

What are Category Intersections? Also described as Category Math (http://meta.wikimedia.org/wiki/Category_math), it is where a wiki page has two or more categories. For instance, at the intersection of the cateogories Locations with per capita incomes over $30,000 (http://en.wikipedia.org/wiki/Category:Locations_with_per_capita_incomes_over_$30,000) and Santa Cruz County, CA (http://en.wikipedia.org/wiki/Category:Santa_Cruz_County,_California) on Wikipedia, one of of the pages you'd find is Boulder Creek (http://en.wikipedia.org/wiki/Boulder_Creek).

I loved this idea so much (and thought it addressed one of the issues I had with a directory in the first place - how to find things if you have to go down category hierarchies to very narrow categories) that I wrote an implementation of it; try it out at Special:Intersections.

If you have any feedback or ideas to improve the interface (I know it's not the most intuitive thing), I'd be love to hear them on the talk page.
