It should be. This is a discussion about art, aesthetics, culture and biology, all topics of intellectual interest.
It's surprising how immature a community which prides itself on intellectualism can be when it comes to genitals, though.
Enough people found it interesting, so yes.
well... HN does kinda have a start-up/tech focus. It'd make sense to moderate in a way that kept people "on topic". If you want general discussion there are better places for that.
Yes, but the guidelines explicitly say "anything that gratifies one's intellectual curiosity". I'm okay with that, I'm here for both things, tech-related or otherwise, as long as it's interesting.
