Wikipatterns is a toolbox, not a recipe book, its content requires a certain knowledge of what a wiki is (here goes the mandatory Wikipedia definition of a wiki ;-). Its target audience is people whose goal is to spur wiki adoption in a community, but it also has some advice for developers, such as how to use WYSIWYG (one of my long lived pet request, since for me wiki syntax = WYSIFUC !).
(*) Wikipatterns isn't limited to a particular wiki software, and they have promised to put the content under a Creative Commons licence. This said I'm currently working on a project using Confluence, and I hope I'll be able to write about it soon.
