The Simplicity of Clojure by Bridget Hillyer and Clinton N. Dreisbach. OSCON 2014.
A great overview of Clojure that covers:
- Clojure Overview
- Collections
- Sequences
- Modeling
- Functions
- Flow Control
- Polymorphism
- State
- Coljure Libraries
Granted they are slides so you need to fill in with other sources of content, such as Clojure for the Brave and True, but they do provide an outline for learning more.
I first saw this in a tweet by Christophe Lalanne.
