I operate a pretty large directory which uses some pretty fancy functions to operate efficiently. One thing that we've struggled with over the years is how to stucture our categories.

We've relied mostly on used user-suggested categories to build our list of about 500 or so, but honestly, it now resembles quite a hodge-podge and doesn't follow any easy to understand logic. We have long wanted to replace the category stucture with something more logical, but where to start?

Of course the mother of all category structures in found in the DMOZ, but my understanding is that if you use even just the category structure you would have to put their editor box on each page which uses the category stucture (basically every page in the directory).

What do you use for your category list in your directory? Am I missing something obvious here?
