Facts do not cease to exist because they are ignored.

- Every PL ranking from RedMonk to TIOBE index indicates that what I'm saying is true;

- Clojure today has more conferences, books, podcasts, jobs and meetups. More than any of other language in its category of languages with strong FP emphasis. It is more popular than Haskell, Elm, Purescript, F#, Elixir, OCaml. Latest JVM survey indicates that it surpassed Scala and has become third most popular JVM language after Java and Kotlin;

- Clojurescript is the most popular alt-js choice (if you don't count Typescript as alt-js). Elm and ReasonML are far less popular;

- If you count by lines of code on Github and Gitlab, Clojure potentially may come second after Emacs Lisp (which is almost four times older than Clojure). Other Lisps wouldn't even be near their numbers.

- And please stop calling it an "improper Lisp." None of the authoritative Lisp scholars have ever indicated this even remotely to be true, in fact many have endorsed Clojure. Clojure can be viewed as a next evolutionary step in development of Lisp. Whether you like it or not, it is slowly spreading wide and beyond JVM (the platform it was initially intended to run on)

It's quite rare to see postings for CL jobs, yet plenty of companies are actively using and hiring for Clojure. It's certainly a far more popular choice for green field development nowadays. Sounds like you're the one who needs to provide citations here and not the other way around.
