This has also been my experience when pleading with clients about not using Wordpress... even when they pay me to research SSGs, they seem to always revert back to WP because that's what the non-engineers know how to use.

Git is not for deployment. Also, hardcoding blog posts in the repo is a dumb solution, and not necessary for a static site. The user built markup should be separate from the code that generates static pages from it.

The aforementioned Movable Type has a pretty graphical interface just like WP. It's just that in the background it generates static files.

It's depressing that 17 years later it still seems to lack a decent competitor.

For just the blogging portion, you can just add the blog posts directly through github (the markdown files for posts).

But yeah, it’s less user friendly. I’m sure someone will make a good solution for this soon.
