If I'm a lazy bum and mostly content to be a lazy bum I will stay a lazy bum. Any interventions that are not doable by a lazy person will not be done. But if I have even a slight preference for being awesome, and there's an intervention that is fairly easy to implement, I want to do it. Insofar as you'd prefer people who share your values to be NOT lazy bums, you should if possible encourage them to be self-improvers.
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.
