Amit Varma was kind enough to pick up some fragments of mine for an interesting article on quizzing. Serious quizzing still remains very niche, a masonic sub-culture of sorts, but it takes a quiz-geek to know there are three ways of looking at every intersection, even if it only seems to be a straight road.
Anyway, as Amit mentions in the end of his post, check out Niranjan's primers (1, 2, 3.) on setting quizzes (to which I've made a small contribution). Perhaps they need a little touching-up, but they're perennially relevant.
