Interesting to note that Julia comes in at #9 on the list, ahead of Scala, Clojure, and Erlang. I still think it's the most underrated programming language of the decade and hope that its usage continues to grow. I know it's touted as a language for numerical computing and scientific research, but I believe it would make a great general purpose language, perhaps even better than Python.
Other than a few minor nitpicks, Julia is genuinely a joy to program in, and the depth of its feature goes very far (multiple dispatch, homoiconicity, genuine macros, sophisticated type system, runtime compilation via LLVM, clean interfacing with C code). I can't say the same for other languages. You can tell the language was designed and not cobbled together in an ad hoc fashion.
