Insufficient value add by the OP. Given that, insufficient expected value add in the comments. (I think that the Textbooks List and Procedural Knowledge Gaps lists belong in Main because the collection of knowledge by commenters is valuable enough, even though the OP is not a huge value add on its own. )
What a great reason!
If I wanted to not just learn that lesson, but reinforce that sort of reasoning in the Less Wrong community (in a welcoming way, naturally), what would you suggest I do? And feel free to PM, as I agree about limiting discussion about where to put threads inside threads.
People want to tell everything instead of telling the best 15 words. They want to learn everything instead of the best 15 words. In this thread, instead post the best 15-words from a book you've read recently (or anything else). It has to stand on its own. It's not a summary, the whole value needs to be contained in those words.
I'll start in the comments below.
(Voted by the Schelling study group as the best exercise of the meeting.)
