I keep thinking a nice client app that is mostly working against a directory of markdown files that "publishes" to an option of fastly/denoland/cloudflare as mostly-static content would be a pretty nice option.

The blog/data directory can be backed up or even using a github repository for long term raw storage.

I'm not a fan of having the same site/application for rendering as editing the blog as it tends to become too much of a big/easy target... ie: Wordpress, how much internet traffic is script bots trying WP exploits?
