I think, for now at least, the discussions of articles should be redirected here to the wiki forum.
Perhaps, next time I see a dev, I'll ask about adding a line of text underneath the Category boxes on all the pages in the wiki, something to the tune of "If you would like to discuss this article, please head over to the
WikiFeedback forum."
I think that would be a decent alternative to having a discussion tab on every page. That way, there will be one concentrated area for discussing hot button topics and asking for help in fleshing out articles.
