Re http://dev.plone.org/plone/ticket/7831 some simple triggers might draw attention to documentation that becomes outdated (or at least deserves review) at product update time.
concerned about how easy it is to add an article
highlight the "good" bits of documentation
reviewed at least each time we make a new Plone release
First improvements to a document might be: (1) a link to Trac, so that any documentation-related issue can be tracked; and (2) an in-document summary of relative tickets.
