I would go with Ruby, Python, JavaScript. You might want to even look at some Lisp dialects, maybe you are one of those people who sees things more like Church than Turing.

They are all comfortable, require a pretty small platform, and provide some instant gratification...the excitement of seeing your code come to life as you type! I think if you simply want to interact with developers, understanding the thrill of creation is more important than knowing what to create.
