That is a joke but not much of one; writing style guides to capture "What is... taste? How do we scale it?" is a project I've actually been involved with. This project brief has defeated many talented people, the least of which being me.
It's often mentionned in HN, but in the same style, I cannot recommend enough "Money stuff" [1] which is Matt Levine's newsletter at Bloomberg. Highly entertaining.

There were a few times when I almost sent him a tweet that he got some logic backwards, but after rereading, I realized that I had misread it, that it's right but confusing.

In the "good old days" they made students memorize passages from great authors and reproduce them. The idea being that this process will force you to think about the structure of their sentences and vocabulary. I used to do this when I was a kid, but I don't think I did it enough to have an impact.
