Knowledge Management is clearly a ubiquitous and important business problem. I've struggled with Knowledge Management in previous roles and deployed a tool called Guru at two different companies. My teams found Guru significantly better than a Wiki because Guru distributes the maintenance load across a team of Authors (experts) and sets verification intervals (ie 1 week, 1 month, 1 year, etc) so that the Author is nudged to re-verify or update the info after the horizon expires. We found such success with the tool, and I enjoyed working with the Guru team on deployment so much, that (full disclosure!!) I now work on Guru's Customer Success team. There was mention in the thread below about no tool being able to replace personal interaction. While I agree with that, Guru is the next best thing I've found so far, especially when teams grow to the point that the "Expert" is getting shoulder-tapped too often to focus on their actual job. Tons of other good ideas below that I don't have time to consume. Check out getguru.com if curious!
