Look at the thousands of people who learned Haskell and then also felt inspired to write a monad tutorial and publish it on the internet. Your search engine will help to see just how many there are.

Contrast with the number of useful applications you can actually install and run that are for some purpose that is not programming.

In fact there are more Haskell textbooks you can read than haskell programs you can install (excluding programs for programming - because that's some pyramid scheme vibe there).

This tells us something, I didn't even suggest what it tells us. What it suggests to you is what you thought of.

And fwiw imho pandoc is extremely useful! And Haskell is great fun and worth your time to learn!

What have you written in haskell that we can use?

Wow, these all look like well crafted. What's your web framework of choice with Haskell?

I build everything with Yesod. I'm sure the others are good too; Servant seems great. But this is the one I started with, and it's served me very well for the past few years.
