Indeed, and as usual XKCD has an explanation for the "someone hasn't heard of everything" phenomenon. https://www.xkcd.com/1053/ https://www.xkcd.com/1053/ However HN does seem to curate specific on topic informative posts, especially early on in the conversation (when everyone is reading, rather than just people looking for replies to their comments). Overall I think I agree with the policy.
