I really like your emacs setup and am wondering if you have your dotfile(s) up anywhere, and/or a quick overview of your setup? I know you have a full emacs course proposed, but I’m curious if there’s something a bit more immediate out there.
My setup for clojure is very basic. clojure-mode, cider and paredit - https://github.com/ludwigpacifici/dotemacs
I use a lot expand-region which is useful for general editing - https://github.com/magnars/expand-region.el
Also, you have a nice chapter about emacs in Clojure for the Brave and True - http://www.braveclojure.com/basic-emacs/
I hope it helps you
