I think it's a problem loop. No one wants to use Clojure because it's hard to impossible finding Clojure Devs. Also no one wants to learn it for the same reasons. The demand is less to non-existent to a point any time spent learning Clojure is unlikely to give any substantial returns.
I would say Clojure more than substantial returns of invested time. Not just the language itself, but also the wider approach to software composition, feature accretion vs backward compatibility, schema'd dynamic typing seem benefictial no matter what your development tools you use. Maybe check out the talks below and see if they don't enRich you as software engineer.
If anyone reading this is in this situation: hi! I've been working in Clojure(&script) for eight years, and I'm looking for full-time work. Email is in my profile.
