It was a success in the sense that we learned a lot. If anyone wants to know about that, a lot of it is in the explanations here:

Some good threads to start with might be https://news.ycombinator.com/item?id=21607844 and https://news.ycombinator.com/item?id=22902490.
These explanations have become pretty stable by now—stable enough that I repeat myself incessantly: https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que...

But it sure does stand out when HN comments are made with the assumption that the fellow HN readership is US. Any time I've tried to highlight how this looks from the outside it's generally met with downvotes, to the point that I self censor comments that I otherwise feel could have enriched this global community.
So, maybe there is the chance in your comments @dang to make a reminder that it serves a global community? It might help soften feelings of any comments that are heavily partisan.
It also becomes apparent when talking about issues such as zoning, and housing. (Every time you hear talk about reassessing houses for taxes I get confused, because in the UK, and Finland, the two countries where I've lived and bought property, we don't have annual taxes that work like that.)
Mostly I bite my tongue and keep quiet, though there have been a few Brexit-related posts over the past few years where I can sometimes be involved.
