Oddly, I do not consider HN to be an „American forum“ at all. I think of it rather as a global community of nerds of all shades and colors, using the language that is used most widely in technology/engineering/science.
I mean that is a large part of what HN is, but not exclusively. As a non-american I frequently see posts that are obviously only on the front page because most people on this site are from Silicon Valley or USA in general. Some examples:
- San Francisco housing crisis: This has been a frequent topic of discussion on HN but I don't think many people outside of San Francisco, let alone outside of USA care a lot about this
- The collapse of silicon valley bank was a huge topic on HN but it was more or less non-existent in the news in my country
- Posts about US politics, such as anything related to Trump or the American Supreme Court
- When a post is specific to a particular country, it's usually indicated in the title, except in the case of the USA
