I know Python, Ruby, JavaScript, and PHP. I often work in all of those in a given month. PHP is my weakest of the four. If I could choose a new language to know, I would choose Clojure. I want to know a lispy functional language, and I'd get a lot of the benefits of the java ecosystem. C or Java or C# might be a better choice, though. They would enable me to do a lot of things I can't currently do, and I'm not entirely sure Clojure would do that.
