What's so intimidating? You don't need much to post here, just a basic grounding in probability theory, decision theory, metaethics, philosophy of mind, philosophy of science, computer science, cognitive bias, evolutionary psychology, the theory of natural selection, artificial intelligence, existential risk, and quantum mechanics - oh, and of course to read a sequence of >600 3000+ word articles. So long as you can do that and you're happy with your every word being subject to the anonymous judgment of a fiercely intelligent community, you're good.
