I was wanting to work with people who cared more about the work they were doing than those I had been working with. I thought functional programming was a way to so this. I thought that by learning these languages that I would find the programming promised land of good tools and good users.
I never found anything like that though. I couldn't find many jobs using these languages and the few I did seemingly were too difficult to be hired in. And I was never successful in evangelizing them in the roles I was already in.
The F# landscape seems to be worse than it was a few years ago. And I am fairly certain it will never change for the better. I think being .net hinders it in a way that the JVM doesn't hinder clojure. C# is a pretty good language and platform and the community is fairly aligned with the Microsoft's direction and influence on the ecosystem.
