Thanks for the answer!
About 2. It's not only HN (but I get your point which is why it could be that they are less talked about and more used). Waht worries me is the LinkedIn job ads for clojurists.
That said, I was pleasantly surprised recently by a search on LinkedIn for Clojure and found some big household names hiring (including several large banks who most people think of as being very conservative).
The number of roles in all of Canada for Clojure is about 40 on LinkedIn, easily less than the number of applications a job hunter could send out in a day.
For what it's worth, I do see some jobs for Clojure in the UK and EU on LinkedIn, not as much as other programming languages, but enough that I think I could get one if I were looking for a Clojure job.
