Static websites are great! I would love for them to be more popular. But a lot of people are locked out by the technical hurdle. "Just use <SSG> and host on <github/netlify/whatever>" does not work for your aunt, parent or SO.
I've tried and went into a different direction and created a desktop app [1] for creating a basic website. Yes it's electron and yes it currently only uploads to Vercel for hosting. But those are things my dad does not care about. I can send him a pre-configured "project" file, so he does not even have to enter any API keys.
EDIT: I've re-read this and this sounds like I'm ranting on your project. Not my intention, I love the bloat free sites md2blog generates. Keep it up!
