The only downside of a fully static site as a blog is not being able to make it a first-class citizen on fedi.
I kinda feel there has to be a way, without running a full-blown fedi instance just for that though. But I don't have the time to see if I can figure out how to abuse ActivityPub this way. 🤔
use reverse proxy magic to serve static files on everywhere except /.well-known/webfinger and some /ap endpoint, and redirect both to a stripped-down activitypub server, something like gotosocial but even less
on the client side you either use JS to pull in the replies or use a proxy (maybe a lua-enabled version of nginx) to rewrite content on the way
the mastodon blog had something about activitypub with static files but your thing would effectively be read only if you did that (as far as i know, anyway)
