Here the author. If you dislike Go then that makes two of us :)

But more seriously, I wrote a bit about the why in https://github.com/rach/pome#why-building-pome

To keep with the simplicity that I was aiming, I wanted a binary. I considered Rust, Haskell or Go (Swift was not opensource yet at the time) but went with Go because the libs that I will need (cron like scheduler, embedding assets, etc).

I had never written something in Go before but if I've known go then maybe I would have pick an other language as I started this project with a learning motivation.
