These "secrets" that are being hidden are basically on the same level as gary tan's list of super uber powerful prompts.

None of it is actually that crazy that everyone else could think up.

What I've noticed in my own experience here is that even when I do share my own prompts/skills few people use them (or alternatively they were so basic that everyone already had their own version).

e.g. If someone doesn't care about xyz before AI, they probably won't after AI even if I serve them it on a silver platter.
