I wonder if there is any wiki software that would actively help curators in grooming it by say: * giving readers the ability to quickly highlight some text/content to mark sections as "out of date" * provide "rot report" views where maintainers can see which pages are the most stale in terms of never being viewed or edited. Sort of highlighting of content which has gone the longest without being seen at all (or possibly, edited).
