Taking Confluence as a popular corporate wiki, there’s no need to dump content so brutally. You could easily write an automated pruning script that does things like; - find pages that haven’t been updated in a while - messages the last editor “this page will be deleted in a week. If you think is should be kept please update it” - a week later deletes the page (or puts it an archive) Probably needs to smart about how it determines age - certain pages tend to get used annually only (eg the annual budget info) All that said, most of the problem of cluttered corporate wikis is simply because their search engines suck. Confluence is particularly bad. The #1 thing you need in a corporate wiki search is results ranked by recency ... most things that happen in a corporation have a half life of 2 weeks before they’re no longer interesting. Relevancy also comes into that of course. The user themself would also be nice to have - a given person with a given role will naturally be more interested in some content and not others, and that’s easy to determine from their search history
