What advantage does this have over say Jekyll?
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.
It doesn't. It's just something you made. Use it or not. Nobody cares.
But yes, diving in and making something that works is a good impulse.
