> I've written applications using Java, Groovy, Clojure and Scala (in that order)

I'd say the most natural pathways for Java programmers upgrading their language skills are:

* from Java, to Groovy, to Clojure

* from Java, to Groovy, to Scala

* from Java, direct to Clojure

* from Java, direct to Scala

Once someone reaches Clojure and Scala, they seem unwilling to give up what they've gained (the simplicity and macros of Clojure, or the higher-order typing of Scala) to switch to something else, even when that something offers more.
