This seems like an answer from someone who filters the industry through Hacker News.

Java's market share is still huge. Clojure never really had a big market share and Ruby is still very popular.

Honest question: Is Ruby (significantly) more popular than Clojure?

More popular, probably, but in no way a better option if you are into functional programing.
