"reputation system" for the wiki
Would it be possible (and do think that it is a good Idea) to create something like a "reputation system" for the wiki. I personally think it is hard to keep the content of a wiki up to date. So it might be a good idea to let people vote whether an article was useful or not if it needs refactoring or if it should be deleted. Then someone who manages the wiki could have a special view where he can see how many times a site was viewed & whether people who accessed it think it is useful. Articles that are not looked at a lot might not be at the right place or have no links to it or maybe the content is out of date. I guess http://stackoverflow.com/ has this realized by enabling users to upvote & downvote questions.
