Use a randomizer to choose someone in your address book and call them immediately (don't give yourself enough time to talk yourself out of it). It is a rush thinking about what to say as the phone is ringing. You are risking your social status (by coming off wierd or awkward, in the case you don't have anything sensible to say) without really harming anyone. On the plus side, you may make a new ally or rekindle an old relationship.
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.
