But I know Clojure is in use in quite a few places, and it has quite a few really capable people supporting it in one way or another. Plus it has good documentation and several books teaching it. That's very different from a slick (and impressive) framework built by one company for themselves. Also, code written for Electric is very specific to Electric. But Clojure is just functional-first Lisp. It's very easy to rewrite in another language, even an imperative language. There wouldn't be a huge paradigm shift translating Clojure to any of half a dozen popular languages.
