Yes, that is a fantastic explanation. My coworker immediately got it, and was simultaneously blown away by the concept of "arity."

Please keep it up.

One area you may be interested in: I've recently been playing around with Incanter (a library for data analysis, similar to R or Python Pandas).

There is a distinct lack of tutorials for using it, and the documentation isn't exactly friendly....

The reason I mention it is because I think data analysis is a place where Clojure absolutely shines, and someone with your expertise could probably work it into useful examples.
