In this short snippet from Clojure Made Simple, Rich Hickey explains how java classes are glorified maps.

I walked through Aphyr's Clojure from the Ground Up chapter on polymorphism today while following along in my repl and it was really good to see the how defmulti/defmethod, definterface, defrecord work similarly and differently.

If you are looking for a good post about Clojure and polymorphism, this is probably the best.

I would like to do the problem set at the bottom of the chapter tomorrow.

Jordan Miller is a new youtuber doing videos about Clojure and programming. This is one of her first and gives a short intro to Clojure.

This playlist is a screencast of creating an Anki clone wth Clojure, ClojureScript, and Datomic.

I watched the first 5 videos today (only ones available as of right now) because, while I work in Clojure, I haven't worked with Datomic and I was curious about it. This screencast isn't for beginners- it assumes you have a basic understanding of Clojure and Clojure project set up, though the creator does write comments so you can follow along. If you are following it like a tutorial, you'll have to pause it often because it is pretty speedy.

I'll probably watch the rest when the come out because I'm curious how they'll use the ClojureScript. I know there's a lot of ways to do the same thing, so watching other people work is very educational.

I'm going to have to watch this one again, so I'm sharing it here as a reminder.
