In fact, I’m doing that right now! Mostly because I want a blog with a graph structure for linking, and most assume you just want a tree of categories, with tags as a seperate set of trees, usually with a depth of one. And it mostly just boils down to those 3 lines, with some additional support for the graph structure (and to force the urls to reflect the path taken, symlinks for all possible paths)
