It’s just so powerful and versatile. I’ve been only using it for less than a year, but you can do most things with clojure, and do them good.
GUI, Web backend, frontend, logic programminc, scripting, CLI tools, and so on.
After you get the hang of it and REPL driven development, your productivity keeps getting more.
One thing that makes me really believe in it is how people that are good with it are so productive with it, I would say more that other languages. There are so many great projects built by a small team or solo devs in clojure.



People suggest matrix but matrix really doesnt replace mattermost for an org.
mattermost is oriented towards org needs. It has boards, playbooks, better levels of access control. Admin panels etc.
We really need a sane Slack alternative that is at least fully free for self hosting.
