> If organizations using Confluence had at least one full time "Wiki Master" position or the like (with resp. superpowers), this wouldn't have to be like that.

I think part of the challenge is finding and retaining this person. It takes a fairly unique kind of person to want/enjoy a (let's be honest) thankless job like managing and maintaining a huge corporate wiki.

Finding good tech writers or information science professionals has always been a difficult task in any company I've been at.

Documentation and wiki writing ends up being side-of-desk work for someone else, and so of course it never gets maintained.
