I assume it's possible, because most people who blog do it, but I struggle to get comfortable posting to a personal blog using a CMS (e.g. Ghost). I can't seem to get over knowing that it's all "out there". It's probably irrational, but still makes me twitchy. My blog is like a journal. I don't like the idea of my journal being at all fragile. Anything other than local-first static HTML feels fragile.

@stefanoStefano Marinelli I definitely understand those concerns, and was using a self-hosted mkdocs install linked up to one of my vps hosts, using git and rsync for deployment, certbot for tls, etc. however, great for documentation but not ideal for blogging. so, looked at ghost, substack, a few others.
so... short version is that I went with micro.blog, which transparently syncs to a personal git repo, and it's all static rendered pages using Hugo templates. it also optionally syncs to one's fedi account if that's desirable. I write my posts on my workstation before doing anything with the blog posting interface. also, it runs under my own domain. so far I've been quite pleased by the service, and it's only about five dollars per month. https://micro.blog
