In its earliest years HN felt to me to be a decidedly American place, steeped in the politics, culture and views you might expect of its origins. Now, there's far more Europeans, Asians - and increasingly Chinese as HN apparently isn't firewalled. The attitudes to many things have moved to being more international, whether that's in terms of politics, healthcare and regulation, or simple corrections to the trivial but often fascinating things that are just done or viewed differently around the world.
Sometimes the split shows up quite clearly with votes going one way when it's mostly the US awake, and quite another once Europe and Asia has had a chance. Early GDPR discussions were probably the clearest follower of this pattern. :)
