This is an excellent tutorial, kudos to the author! As an additional supplement for beginners I'd also suggest solving some coding challenges in Clojure on pages like HackerRank. It's addictive fun and supplies cool problems to solve at will, made a big difference for me.

The http://www.4clojure.com/ site does a great job of this.

Absolutely. The quality of other's solutions and the more Clojure centric atmosphere are pluses compared to for ex. HackerRank. The reason why I personally chose HackerRank over 4clojure was the Ranking/Badge/Percentile central theme. I just got hooked on competing with other people and upping my profile. Though now I am thinking I should give 4clojure another go..
