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.
Here's a possible norm:
If you'd like to ask an elementary-level question, first look up just one word — any word associated with the topic, using your favorite search engine, encyclopedia, or other reference. Then ask your question with some reference to the results you got.
