After a discussion on a page has died down for several weeks, you (if you can be smart and respectful at the same time) might replace the discussion with a summary of arguments, as though you were (!) writing an encyclopedia article stating the arguments from an unbiased point of view. If anyone believes his argument has been misrepresented, he can always go back and look at the "Recent Changes" and see the old version.
Summarizing and otherwise cleaning up a discussion, and integrating results of it in with the article commented on, is called refactoring. See also RefactoringPolicy.
