Secondly because I think most of this community would like to actually make the world a saner place, and those skills are really handy when trying to explain to some intelligent-but-uninitiated schlub why a given silly belief or deduction is in fact silly, or conversely why any of the tools of rationality we use here are in fact rational.

If you have significant experience with this part I'd enjoy seeing an article on it. Significant here means that you've seen enough people not just "lose the argument," but actually go on to apply what you tried to teach them, to get a good feel for what teaches people instead of merely winning. I definitely don't think we need a post on how to win arguments.
