I'm the person who submitted it. I thought it was interesting in part because it talks about some of the cities with a significant number of such people.

I'm a demographic outlier with zero social connections via HN. No one on HN routinely emails me, chats with me on the social platform formerly known as Twitter, meets me for coffee in person, etc.

So the only feedback I have is upvotes, downvotes, flags and comments and that's frequently difficult to decifer.

I submit things I think are interesting and accept that most of what I submit will be roundly ignored. But then this seems true for most submissions, so it's not a strong signal (shrug).

I have no idea why this got upvoted enough to briefly make the front page.

Which of my submissions does well and which doesn't frequently baffles me. I no longer waste a lot of time trying to figure it out.

Good place for 1%ers to argue with 10%ers while 0.1%ers look on and laugh /s
