When all is said and done, I would like a picture like http://ontology.teknowledge.com:8080/rsigma/sumo-1.36classes.pdf and when I click on a category, I'm sent to a category page which lists the immediate superclasses and subclasses (editable), gives an editable description of the category, gives a link to the recent changes in that category (including all changes in its subcategories), a link that allows searching in the articles of that category and its subcategories, and a link to a complete alphabetical list of all Wikipedia articles belonging to that category and its subcategories.
(I'm not suggesting that we adopt SUMO http://ontology.teknowledge.com/ because these people live in a world where fungi are plants and where real numbers, imaginary numbers and complex numbers are disjoint.)
