I think that which technology to use (wiki, shared drive, etc) is not as important as the fact that there should be one AND ONLY ONE place where documentation lives. Yeah, having to jump around across many repositories is one of the big (technological) impediments to knowledge management working well. But in most companies you'll never manage to get down to just one repository. I believe the key is to have a really good search engine that indexes across all those disparate repositories and allows one to find relevant content regardless of where it's stored. That, of course, is not an easy problem to solve.
