As Nick mentioned on another topic, we should flesh out our taxonomy a bit more. It is my opinion that the breadcrumbs, URLs, and taxonomy should all match. They are one in the same, in my mind.
So, I have been setting up URLs as such, nut have been slacking on makin the taxonomy match:
Motors
Francine
Tempo
Blazer
Rec
Camping
Tech
Creating a Drupal Module book (needs sub-category?)
Opinion (flat currently, I do believe)
Reviews
(one for each section: motors, rec, tech, opinion)
There's probably more I'm missing. Like the blog sections.
