I feel the same, but it's an unavoidable cycle IMHO. Any subculture that becomes popular gets diluted by more average people, and the content becomes more basic and banal. You can flag and downvote, but eventually there are enough people who treat a platform like HN as a general discussion board, without regard for cultural alignment. It seems that stuff like politics and random recipes are on the rise, but it's not against the rules, so maybe it really is just a general discussion board that's evolving into the mainstream.
