The codebase was democracy-related civic tech software. I was a bit biased against Clojure because I wished for the world to show up in the codebase, but it was written in an uncommon language that scared away most every coder who showed up with curiosity.
Probably just the wrong language for the culture I wished to exist around the software. Plus the maintainers used Rich's essays to emphasize their desired ethos of "singular vision" development, which I admittedly became resentful of.
