If I was going to do a blog today, I'd dump hand written HTML into an S3 bucket and call it a day.
The static site generators are nice, but it's really not a huge deal to spin up a few common css classes and maintain a little bit of mental discipline.
I think using a blog to communicate your ideas and skills is great. I think making the blog tech stack itself representative of those things seems distracting. Not everything has to be a smartass ego implementation. As long as you spend 5 minutes testing on mobile, your audience probably won't notice a damn thing the next time it touches the front page of HN or wherever.
Static HTML will also hold up a lot better if a post gets popular than a heavyweight dynamic site framework will.
I was handwriting HTML for a while but found that I write a lot more with an actual CMS. At the end of the day it doesn’t matter what your setup is as long as it helps you write as much as possible.
