Look at a discussion page here or eg on wikipedia. It tends to turn into a mess. One nice way to avoid the mess would be to set it a discussion page as a blog so each new comment is a separate post. One issue is, would there be a way to do this for all new discussion pages by default somehow? Setting up the blog means inserting a preprocessor directive; and that could somehow happen automatically when the discussion page is first created. (Creating a bunch of empty discussion pages with such directives ahead of time would be silly.) Maybe some kind of new page template system would do the trick, so pages matching */Discussion start off as a clone of DiscussionTemplate. Although the first person to try to create the discussion page would still end up in an edit page with that template, which is not ideal. Hmm. Another issue is that discussions really want to be threaded. Does that mean that a page like foo/discussion/question should have its own foo/discussion/question/(discussion?)/answer page? Of course, rss feeds don't handle threading, and of course doing this might be dependant on the issue above. Worrying about threading may be overkill.
