Hidden Mysteries of the Bayesian Conspiracy

Jeff Atwood recommends that everyone read an Intuitive Explanation of Bayesian Reasoning in order to become an initiate in the Bayesian conspiracy. What he doesn't tell you is that Bayes' theorem is only the outermost ring of the Bayesian Conspiracy. Once you've been initiated and spent the necessary apprenticeship bringing beer to the poobahs, you will begin to hear of something called "Bayesian Belief Networks". They're what all the Illuminati use. Is Jeff ignorant of Bayesian networks or is he -- perhaps -- all too knowledgeable and withholding information? If so, for what nefarious purpose?
