Ask HN: Why are you programming your hobby projects in a niche language?

My niche language is Racket. I like it because I like Schemes more than Common Lisps and I think it is the most accessible Scheme. It improves on some of the issues I have with my main language, Python, mostly around creating an executable. If I'm being honest, I also get a dopamine hit from using a niche language, but maybe I'm not the only one who feels that way.
