I have created non trivial projects in PHP and Ruby and have used a lot of other languages to do things before moving to Clojure... probably about 5 years programming before using my first lisp.

For me I find that s-expressions are the easiest thing to comprehend. Every other language is loaded with syntax and with lisp it's just mainly just (function args).

I wanted to test your argument and I have never looked at common lisp before, I just skimmed some source code from this project https://github.com/stumpwm/stumpwm and it's extremely easy for me to parse.

Comparing this to new variants of Javasscript that seem to come out biannually with some new syntax, I have no idea what's going on and have to look up references on syntax to begin to understand anything.

I guess at the end it's subjective, but lisps have ruined other languages for me.
