I think you're overestimating the popularity of Clojure. While it's not as totally obscure as many other Lisp, Scheme or Lisp-like language implementations, it's not very widely used at all. Its penetration is minimal, even compared to Scala (which has seen much more significant usage, but still pales in comparison to Java). While Clojure is a step in a better direction, I don't think it's gaining traction all that quickly. There's a whole lot of existing Java and Scala code that would need to be completely discarded or ignored in order for Clojure's usage to be considered as having any impact.
