I use one that I wrote from scratch with Flask. I love the simplicity of both its code & UI. Recently added an admin panel so I can even edit posts while commuting. It's hosted on a 5$/month Vultr VPS. Had lot of fun trying to make it "secure".
In my case the big inconvenience is that I spend more time developing/improving it than actually writing articles.
It seems that the tool is inspired by the 'IT crowd'. IRL, unfortunately people may skip the first steps thinking that they are taken as idiots.
