I'm going to have to mightily disagree there. The news threads in D&D, at least the good ones, are still meant to become in-depth and people are still meant to take and critique opinions, it's not "chat". The tags for [Discussion]'s and [News] were originally intended to clean things up, aesthetically speaking, so people could sort through the kinds of topics you'd see in D&D. News threads are still kind of a foil to the discussion threads, but they're supposed to be just as in depth and thought provoking - people need to get away from the formula of "link to thread topic + a "do you agree?" statement = discuss!" and add some questions or take a position on the effects of that particular news event.
Think of it this way, D&D is your Social Studies/Political Science/Debate Club class and Chit-Chat Cafe is your creative writing class. Some formalized structure on what to discuss, but freedom to choose how you talk about it. What separates them isn't so much the types of content being discussed, it's the ways in which they're being talked about. But I agree, CCC needs to get away from "bold the question + answer below = leave" formula and get back to just being about raw, light discussion of ideas and other chatter not covered in D&D. But pilfering more from D&D is not how you fix that.
Also, lets make sure that the issues are actual structural problems and not because of some other variable like the user-base, moderation, types of topics being made, etc, before we try and tinker with how things are set up. Best way to start fixing that would be to re-enforce our regulation of SPAM policies, 4/25 rule, etc, because I think that the care-free attitude when it comes to those things helps promote the lazy posting styles that I believe are the real culprit here.
