Personally I think that it would be a good way for each individual employee in a business to provide information from the diffirents point of views, exprience and particular field. Wiki is a little like a website so other important bits of information can be provided, such as pictures. Also users can be removed if they misbehave. If a nesscary other users entries can be edited or delelted. A big plus is that pages can be added by users to provide extra content.
