I found this blog while surfing the web and I've found it very enlightening. Specifically in the realms of world building, character design, and a whole matter of other things. Basically the author rants on a specific topic on his own likes and dislikes in fantasy and how one should properly structure a story.
Warning! Author occasionally uses harsh language, and even worse, constantly bashes Robert Jordon. Use his advice on your own terms, some of it I agree with and some I don't.
