Hi! John from Ghost here - Ghost has no bloated styles or scripts which are injected by default. You have full control of the frontend and can make it as minimal (or maximal) as you like.
My answer to the OP would be:
If you want to write (on a blog) then do literally anything but turn your blog into a development project that you'll definitely never finish - because it just becomes the excuse for not writing. (almost all developer blogs)
If you want a fun developer project to experiment with your personal website, and messing with new technology is the goal, then this stack sounds like a lot of fun. It also sounds like it will be obsolete and no longer shiny in 12 months, but again, if this is your goal then you probably don't care.
TLDR: developer tools will usually end up being great for development, publishing tools end up being great for publishing. Pick the one that suits your desired outcome best.
You can write your own theme still. I wrote my own. Mine serves 2.6kB for CSS and 16kB for app-specific javascript--mostly for highlighting of code blocks
I agree, but then really you're not interested in creating blog content per-se, but in exercising your engineering skills. I think it's important to be honest about that intention both with your audience and yourself when writing articles like this.
+1 for this. I use Posthaven because it's the simplest way for me to publish blog posts plain and simple (and has been for years.)
A lot of devs get excited by the idea of building a blog and not of actually writing the content. You've got to actually have ideas to share and be prepared to put in the time to write posts.
I wouldn't even think about tech before you've got a backlog of at least 2 or 3 posts.
I recommend reading through some of my criteria (ability to use npm modules, TypeScript React components, etc). May be possible with Wordpress (haven't tried it) but sounds like an uphill battle.
