You caught the writing vs tool part well :)
I am kind of ideologically motivated about site minimalism (no JS, minimal CSS), which is why I didn't go down the route of medium. Medium is probably the simplest, but as a reader I hate their UI, especially when I have a habit of highlights the para that I am reading and they bring up their annoying share function.
ghost.org is kinda outside my pricing for a trivial blog. 29 USD per month is not in my planned budget, atleast not with the content that I have in my mind now.
Sure, I can answer all of these questions later, once I get an audience, but I was hoping that someone here already might have found a solution that I can use immediately.
Guess I will resort to my backup plan then, have a basic HTML template and copy paste it for each article and edit the content.
