it already has reached an unprecedented level of adoption for a Lisp used in commercial software. But I agree with you - it would be nice to see it grow faster and bigger.
From technical evaluation - Clojure has an amazing ecosystem. But having technologically superior toolset does not guarantee success, nimlang is a good example.
What Clojure needs today is better marketing. It is fashionable to blame Cognitect (basically for anything), but the truth is - they are not a big company. Even if they really wanted it - they don't have enough people to drive it to wider success.
There are a few large companies using Clojure in production today, companies like Apple, Walmart and Cisco. It would be nice if they recognized the importance of Clojure and put some effort to evangelize for it, support initiatives like ClojuristsTogether, sponsor Clojure events.

From my own experience - the reality is the opposite. There are too many people interested in Clojure, but not enough developers with real Clojure experience. And companies using Clojure desperately want experienced Clojurists and often willing to pay more. It's disproportionate - we need more companies using Clojure, willing to hire juniors. We need to improve the funnel, making it easy to get into Clojure and become an expert fast.
