It's all there to be used, it's just unfortunately Haskell proponents seem not to talk about it as much. Most of the discussion is around "interesting" stuff.
My company does everything in Haskell, but it's almost all just boring plumbing code. APIs, JSON, databases, HTTP stuff, HTML templating, etc. It works great.
Exactly this. I've been meaning to write a blog post about what my team does with Haskell for the last 3 years, and while I think there are some gems of information we could provide to the world, at the end of the day it's incredibly boring stuff that works well for us and isn't really worth mentioning because it's not that different from what everyone else is doing with their own favorite language and tooling.
