If I grab an old Haskell project, even one without any external dependencies, I can often safely assume that it won't build any more with any recent version of GHC because everything has been changed just a little tiny bit.
That's an issue that would more affect experienced/long-term users than newcomers to haskell. I haven't used it myself. I'm just pointing at one person's perspective - someone who professes to still like Haskell - about why it's no longer a first choice.
