    "So What's Wrong With Taxonomies
    Following in the footsteps of the Dewey Decimal System, Yahoo took a highly pre-coordinate approach, attempting to create controlled vocabulary terms (i.e., names of categories) for every imaginable subject. The result? An informal count suggests more than 67,000 categories in Yahoo with roughly 4 to 8 levels of hierarchy between the main page and actual content. That's a lot of vocabulary to manage. Portals that take this approach wind up growing an enormous category structure that constrains their ability to adapt."
