Haskell needs more content like this to show people how approachable it is, and especially when they're more up to date and more in line with recent best practices in using haskell.
As long as we're not all doing burrito tutorials, the more people that engage with Haskell (and write posts about it), especially simple, straight to the point ones like this the better.
I personally have written a guide on how to build practical APIs in Haskell that is now quite outdated[0], and while I tried to go from zero, it is almost certainly not a good entry guide. Glad to see more people taking stabs at it.
