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.
But yes, diving in and making something that works is a good impulse.
It doesn't. It's just something you made. Use it or not. Nobody cares.
