Great article overall, but it makes the same mistake as many other Clojure overviews: implying that STM is the only means of managing state. Clojure, in fact has four main ways to do state, one of which is a (thread-local) normal variable. Each is appropriate for a different sort of stateful operation; STM is the most complicated.
It is not a great article overall. It is well written, and conveys a lot of enthusiasm, but has no insightfull/new content in it. I've read every clojure news and article for six months, and this just basically rehashes every "I love clojure article" i ever read.
If you've been devouring every bit of Clojure-related writing (which I've also been trying to do), then as swannodette said to you elsewhere on this page, you very well may not be the intended audience :)
