Alcoholics Anonymous is famously ineffective, but separate from that: What's your point here? Being a christian is not the same as subjecting christian practices to rigorous examination to test for effectiveness. The question the original asker asked about was not 'Does religion have any worth' but 'Should I become a practicing christian to avoid burning in hell for eternity"
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.
