I thought you might be trolling. But then when I looked at the Clojure repo on Github https://github.com/clojure/clojure the last commit was 2 months back. There is some merit in your arguments.
Clojure evolves slowly and deliberately -- it gets about one release a year (with various prereleases) so "2 months" between commits isn't a big deal. I consider it a "feature" because it means Clojure is extremely stable -- which is great for us at work given that we've used it in production for a dozen years at this point and have been able to run alpha builds in production safely during nearly all of that time.
