The exercises are very interesting to this community I think and maybe I will write a dedicated discussion post.
Write a main post! Summarizing a widely acclaimed book about a rationality-related topic of interest to many LessWrongers surely constitutes worthy subject matter.
I am going to write it in discussion. If the moderators feel it belongs in main they can move it.
If it's worth saying, but not worth its own post, even in Discussion, it goes here.
