Guides to what are generally (at a certain level, anyway) formal processes I find very interesting -- from various Linux howtos to the Anarchist's Handbook. Writing and listing generally implies some kind of thought, and the very act of authorship automatically selects a person who knows what they are talking about. Open documents are more interesting because of the commenting and revision process. (The reascent of micro-publication - the first time being pamphlets - has allowed us to codify much smaller processes. Weblogs are very good at this, but I'd like to see more posts being expanded into full documents.)
With this in mind, as a good example of what I mean and interesting reading in its own right, here's how to respond to planning applications. That is, ones you don't like.
