The antithesis of this is exactly why I asked the question. I was reminded of a tweet/post describing that most blogs have a single post: the one that describes how the author built their own static site generator/blog framework. After that, they are too tired/unmotivated to write anything else.

I was on WordPress. Now I’m on Jekyll. I occasionally think of changing the theme, then I remember how little that will benefit me or my few readers.

THIS!

I'm on Hugo now, and have used both self-hosted and .com (free) versions of Wordpress. Which of the 3 do you think I wrote the most when I was in it?

Yeah, free wordpress is limited, if not open-source, blah-blah-blah. But it's a few clicks to create, easy to write the posts/have drafts/change theme. And I would argue that having limited themes on free can actually be a positive thing. You have a few options, chose something and start writing.

Having to write in any other editor (to have grammar checking), then paste on VS Code, deploy... it just takes more time. And this is without managing any media, which I just upload to imgur and use the link...

This is good advice, for anything that can be tinkered with. Just as applicable to setting up a window manager on Linux, for example. It's an amazing rabbit hole, but it can consume you.
