| 61448432 | Local Adoption. The community is very much concentrated in the US, with the exception of London. In the rest of Europe, not so much. In Belgium we hardly get 6 to 10 people joining a meetup. You see it in conferences too: Clojure presence is much higher at US conferences. | adoption | ||

| 61455773 | It's a fairly insular community. | adoption | ||
| 61463826 | In Japan... * Very little developer use with clojure. * it is too hard to find clojure developer. * it is too hard to find clojure documents for **non-lisp** programmer (I was non-lisp programmer before use clojure, but I am joyful **lisp style** programming with Clojure). | adoption | ||
| 61506717 | Not mature enough language yet to be mainstream in corporate datacenters who think .NET is all you need. | adoption |
