Know what'd be highly useful? More on practical applications for plain old chimpanzee tribal politics. That is, the whole reason evolution hit upon general intelligence for us in the first place. Call it "micropolitics" to distinguish it from "show business for ugly people."
I've been applying the lessons of LessWrong a fair bit lately in micropolitics. Mostly Wikimedia-related stuff. If I say so myself, I've had some recent success putting WYSIWYG back on the agenda, including inspiring a very promising new approach. And a couple of other things that are in progress. But then, Wikimedia and Wikipedia are the deep end as far as quickly learning to work with others goes.
So, how are others going with applying rationality to micropolitics? Remember, you grew that brain at all to do tribal politics. You're naturally good at this.
There is a tendency to downvote articles and commentaries with a political subtext with a remark on how politics is the mind-killer. I completely understand that nobody wants his mind to be killed, however, I disagree on the employed methods. I don't think anybody can really afford to ignore politics. It's a fact about any group of even a handful of people. Thus instead of shunning politics I think it's better to build one's rational defenses. Understanding that politics is a problem is only the first step. If you stop there, there will always be a big part of life where you are not rational. Therefore I suggest that, as long as it doesn't get out of hands, there should always be room for political discussions if not on the main site at least in the discussion section.
