Greg tells his story about 7 must haves for a ideal wordpress them design and structure. He has some good point of view and in all the 7 “must haves” I can agree to all of them excepts the one with the big / large footer. I think that the footer is just for copyright stuff and re-writing the urls from your top menu. But this depends from blog to blog layout.
Anyway a huge footer design isn’t good if you have nothing to show there. If you stick with a clean and simple design you should maintain this “from the head to the feet”.
