The documentation commons page 2

This is the part of the site we are most proud of. When a topic keeps being re-asked, the community promotes it: the content moves onto a page with named maintainers, a revision history, a review date, and a backlink to the discussion it came from. Promotions are argued in doc review in public, and a page nobody will maintain does not get promoted.
