Given Elizier Yudowksy's Peggy Sue parody, is there anything inherent innane about the Peggy Sue fanfic type? If so, I've missed it- what is it?
It's similar to the Mary Sue problem and Eliezer's rule of fanfiction. If you give Harry Potter knowledge of the future, you have to give it to Voldemort too, but that can render both of their sets of knowledge irrelevant and become a self referential clusterfuck to write so probably just don't. If only the main character has knowledge of the future, it tends to become a Mary Sue fic where you replace power with knowledge.

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.
