On WikiProjects: The performance of collaboration projects varies almost as drastically as does the quality of Wikipedia's articles. At some ends, we have some quite impressive organisations - such as WProj Military history - that are very hands-on. At others, there are some quite useless projects that seem to exist simply for the sake of existing. There are still others - such as WProj Law - that aren't very 'collaborative' but do provide some useful tools and resources for improving the parallell subject area: for example, in my experience, WProj Law has little editor colloboration but, by virtue of its in-depth indexes of law articles, is useful for identifying articles that need improvement.
