Recently saw an example of somebody who vibe coded a tool to mass export the contents of a 'Confluence' wiki into an instance of self hosted mediawiki, preserving everything.
replyMediawiki as a whole has a feature set that 95% of organizations will only scratch the surface of. There's a ridiculous number of possible plugins and customization if you have somebody who knows what they're doing with it.
The majority of companies that need an internal KB/wiki do not have as complex needs or use cases as wikipedia itself or the wikimedia foundation.
I've been at more than one company that migrated _from_ MediaWiki to Confluence. It usually boils down to "non-developers have to use this and Markdown+plugins is hard".
replyTurns out no matter how much better the thing is, the users have to know what they're doing more than the operators do.
