No idea. I don't know what Jekyll is; I'm not really a web developer and I'm in the early stages of learning Rails.
I read that talk by Maciej Ceglowski and it made me really want to build something of my own, so I did.
There are probably other solutions out there that do the same thing, but I really wanted to roll up my sleeves, write something, and fling it out into the ether to see what happened.
