I feel I see Scala brought up in response to almost every Clojure post, but I can't tell why. They seem like polar opposites. Clojure has a simple syntax and dynamic typing and no classes, while Scala has a complex syntax and classes and static typing with inference. Why would someone looking for one be interested in the other? Is it just because they both run on the JVM? For all my Clojure projects, I picked the language despite that, not because of it. It's merely an implementation detail.
