We don’t necessarily do good lisp things; we use Common Lisp because macros and easy DSLs allows us to use CL for everything we do while using, for us, the best dev and debugging env in the world. So we want to do the exploration, building, debugging all in CL and after that compile, possibly, to something better depending. We trade for that a little bit of inconvenience (as in; leaky abstraction), but it’s worth it the past 30+ years.

For learning cl, the reddit lisp subreddit is good and has the current best ones on it. Lately there is a guy making a gui (clog) who is doing good work for spreading general lisp love by making it modern. Including tutorials. And there are others too.
