A "meeting" mindset implies equal footing and good intentions, which should be the foundation for any kind of positive human interaction.
Beware of 'should'. Subscribing to this ideal of equality rules out all sorts of positive human interactions that are not equal yet still beneficial. In fact, limiting oneself to human interactions on an equal footing would be outright socially crippling.
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.
