I’d say that the value of Haskell is in all of the lessons we learn from the research that it enables. Language designers are constantly looking to languages like Haskell for well thought-out / sound features they can add to make programming easier in other languages. I’m not sure why, but Haskell is an amazing hotbed for experimentation with new language features.
You don’t have to use Haskell directly to benefit from it.
Saying that it’s a shibboleth—well, that’s kind of a crass way to dismiss an entire community. It’s rude and not insightful.
The error of your rudeness has nothing to do with whether great software exists written in Haskell (which, of course, it—including , but not limited to, pandoc and PostgREST—does.)
Allowing for your (silly) premise, I use XMonad and Pandoc all the time and they are great.
Of course, the quality of a language is at best weakly correlated, and at worst anticorrelated, with the amount of useful software that is written using it.
I’m not trying to “get vengeance” or “show you the error of your ways”.
Your comment was dismissive, and I’m pointing it out because if nobody responds to people making rude comments, other people will think it’s okay to make comments like yours.
