"That Alien Message" read like a science fiction short story at first, and then delivered a number of abnormally deep insights. Ideas so new (or ways of seeing so new) get to my brain 5-6 times a year top.

"Twelve virtues" however... well, I started skimming at the fourth virtue. Most of the content was a restatement of things I already agree with.

Maybe your audience (HN, Reddit) is enough into rationality to care more about very rational discussions (like the AI-Box problem) than about discussions of rationality itself (like "Twelve Virtues").
