I think this post is very good (note: I am the author).
Nietzsche is brought up often in different contexts related to ethics, politics, and the best way to live. This post is the best summary on the Internet of his substantive moral theory, as opposed to vague gesturing based on selected quotes. So it’s useful for people who
are interested in what Nietzsche’s arguments, as a result of their secondhand impressions
have specific questions like “Why does Nietzsche think that the best people are more important”
want to know whether something can be well-described as “Nietzschean”
It’s able to answer questions like this and describe Nietzsche’s moral theory concisely because it focuses on his lines of argument and avoids any description of his metaphors or historical narratives: no references are made to the Ubermensch, Last Man, the “death of God,” the blond beast, or other concepts that aren’t needed for an analytic account of his theory.
I think this post is very funny (disclaimer: I wrote this post).
A number of commenters (both here and on r/slatestarcodex) think it’s also profound, basically because of its reference to the anti-critical-thinking position better argued in the Michael Huemer paper that I cite about halfway through the post.
The question of when to defer to experts and when to think for yourself is important. This post is fun as satire or hyperbole, though it ultimately doesn’t take any real stance on the question.
