What's the difference between the FAQ and the Cookbook? I.e. why answers on how to access configuration options or how to avoid unicode errors can't be given in a cookbook?
I would guess that the FAQ is for short answers. The cookbook would become hard to navigate if it had dozens of one-paragraph articles. The FAQ can also link to Cookbook articles; e.g., to emphasize troubleshooting issues that come up incessantly. New users often don't know what exactly they're looking for, so they may not realize that a certain Cookbook article addresses their issue.
