Ron Edwards' essays and posts on the Forge, plus a post there by Paul Czege, have done more to improve my GMing than any other single piece of advice.if it came from the forge you can be pretty much 100% certain its wrong, terrible advice and you should run as fast as you can in the opposite direction if you want to have a long term, healthy campaign with well adjusted adults.
The only other things I can think of that come close are Chapter 8 of Moldvay Basic, and the original Oriental Adventures.
