Clojure's great. While I like static typing in general, I see a better chance of long-term success in Clojure over Scala. With Scala, there's nothing wrong with the language, but the amount of Java-in-Scala code I've seen has convinced me that there's unintended cultural risk-- at least in the enterprise, where software has been done wrong for decades-- while Clojure forces people to be exposed to new ways of doing things.

There's some progress being made on static typing in Clojure, too: https://github.com/clojure/core.typed

Still fairly early days on that though (missing protocols and rest parameters are the big issues I think)
