Wiki Wake-Up Call and Use Cases
Good discussion of how wikis are used (because you can't simply assume they'll work for everything). The author lists a range of user-types, from single-user wikis to public megawikis like Wikipedia. He also offers a set of use cases - some good suggestions to which experienced wikinauts could no doubt contribute.

I rarely use Wikipedia anymore as an example of a wiki because I find that for people who don’t know what a wiki is, there’s often a negative connotation to the idea that usually has little applicability to the people with whom I’m talking. I’ve also been focusing more on how to use wikis to address specific business issues/problems and your use cases above give me some more ideas on how to do that.
