It seems to me that, unless one is already a powerful person, the best thing one can do to gain optimization power is building relationships with people more powerful than oneself. To the extant that this easily trumps the vast majority of other failings (epistemic rationality wise) as discussed on LW. So why aren't we discussing how to do better at this regularly? A couple explanations immediately leap to mind:
Not a core competency of the sort of people LW attracts.
Rewards not as immediate as the sort of epiphany porn that some of LW generates.
Ugh fields. Especially in regard to things that are considered manipulative when reasoned about explicitly, even though we all do them all the time anyway.
Insofar as MIRI folk seem to be friends with Jaan Tallin and Thiel etc. they appear to be trying to do this, though they don't seem to be teaching it as a great idea. But organizationally, if you're trying to optimize the world in a more rational way, spreading rationality might be a better way than trying to befriend less rational powerful people. Obviously this is less effective on a more personal basis.
r/Fitness does a weekly "Moronic Monday", a judgment-free thread where people can ask questions that they would ordinarily feel embarrassed for not knowing the answer to. I thought this seemed like a useful thing to have here - after all, the concepts discussed on LessWrong are probably at least a little harder to grasp than those of weightlifting. Plus, I have a few stupid questions of my own, so it doesn't seem unreasonable that other people might as well.
