Sounds like the lisp programmer skillset doesn't have a strong overlap with the java/python/javascript programmer skillset. Makes me want to learn more lisp. :)
There is some overlap with javascript because it's the only one of the three that offers uncrippled lambdas. Or I may be wrong about that; did Java finally add them?
Even before Java 8, Java had inner classes that if you squinted at them right looked like very syntactically awkward lambdas (indeed, Java 8 lambdas compile down to something that looks an awfully lot like an inner class).
