Interesting to see that Erlang and Lisp are missing. Whenever possible I'm doing new development in Erlang (with C linked-in drivers where needed for performance).
Personally, I'm moving away from Java and languages that target the JVM. I find that Erlang lets me express solutions more concisely and the Erlang emulator/vm has many of the tools needed for massively scalable, distributed, fault-tolerant systems built-in.
