Not necessarily a culture shift - assuming you mean IRL culture, not HN culture - but rather a sign of HN's much increased popularity in recent years, outside the thoughtful nerd circle.
I did mean HN culture, but you make a really good point either way. Maybe I need to find a yet-more-secluded corner, where the rest of the world can’t encroach so easily
The moderation team does a good enough job already; they will and should continue to stick to their guns about "good faith" discussions and that will be enough of a frustration to people repeatedly posting thoughtless or incurious comments that most discussions will continue to be reasonable and sensible. There are still pockets of that here. I think the other commenter nailed it about this being a result of increased popularity but I also think that will cool down as the less curious learn to prefer different communities.
