This is a great reply. Real question: Why hasn't the same happened to HN? To be fair, there are some arguments that play out over and over again: SF crime & homelessness, Bay Area housing, US taxes, central banks "printing money", office vs work-from-home, feeling forced to adopt liberal social views / stances at a tech company (Black Lives Matter, LGBTIQ+), etc.

And somehow, there is still enough good, new content to keep the conversations fresh. Some of the best are when someone shares a personal story, then there are tens or hundreds of follow-up posts -- generally supportive or inquisitive.
