There's an interesting intersection between "Money Stuff" (Matt Levine's newsletter) readers and HN participants. I often see Matt link to articles that were on the front page of HN the day before and often see front page HN articles that we're in Matt's links from his newsletter that morning.
Could be coincidence (interesting articles are interesting articles!) or a more closely linked feedback loop.
Not a coincidence -- he links to the OP's link in yesterday's column when discussing precisely that similar problem. It is likely how the OP found this older article; I know I read it earlier today due to Matt's link.
