Clojure is a great language for small creative teams to achieve great(relatively) things. It's difficult to understand that from a startup mindset of hacker news where money is no problem and peace of mind is an after thought.
If you are a budget constrained individual living in a third world country with nothing to invest but your intellect and time, Clojure is a very good language. It lets you to - 1. Create relatively large systems without pulling your hair out. 2. Juggle between different projects with relative ease. Great for managing a projects in maintenance mode. Great for contractors with long term support contracts. 3. Realize your vision of a complete product with relatively low time and money.
Overall, it's a way of doing effective programming. It's probably not a good way of making money if the focus is to siphon investor money with a large team and millions of lines to show for.
