This book format lends itself very nicely to a book club. I was in one with both new and experienced gophers. The mistakes are great discussion points. The veterans got to share stories when they've made whatever mistake or how they've avoided it over the years. The noobs often made comparisons with other languages.

A little secret about the book is a lot of the "mistakes" are introductions to some aspect of Go worded as a mistake. "Not using fuzzing" and "Not using errgroup" are a couple of examples.
