Wikibooks:Avoid instruction creep

Instruction creep is a wiki phenomenon that occurs when a community's written rules evolve into something other than what they are supposed to be: straightforward explanations of community norms. It is important that policies and guidelines do not themselves become a source of problems.

In particular:
 * Ensure that every rule has a good reason.
 * Keep explanations simple and to the point. Use essays to elaborate.
 * Separate distinct points, to aid clarity and purpose.
 * Leave room for Wikibookians to use common sense.
 * Remove or modify any stated requirement which is found to lack community consensus.
