I was pretty annoyed of wordpress. Updates for files/themes/plugins i never used, but where shipped in the default install and have a big bug/vuln/whatever. Or use the distribution shipped version, but then you have to stay with an old (but probably stable and maintained) version.
At work i got some information about static site generators, how nice they can be (fast, reliable, easy to move, less resources required, ..) so i checked out a couple of them and found hugo to be the one i will go with.
Lets see how it works :)
