Holly Lisle's Web-Empire
This author will give you plenty to think about and reading her blog, or sifting through her site's cornucopia of resources will we time well spent. She can improve your writing just by listening to her advice. Her articles on Worldbuilding are very well thought out and very much worth reading. Her article on Why Everyone Shouldn't Like You is highly recommended, as is her tongue in cheek piece on How to Write Suckitudinous Fiction.
