One thing that sort of annoys me about ActivityPub is that, as far as I can tell, there's no good way to have a statically generated ActivityPub feed that can be followed by Mastodon users
E.g. https://github.com/ufosc/TheIsolator is a way to publish your static site updates, on deploy, to your AP followers. I've seen similar tools/attempts for Hugo and Cobalt.
I have no experience with this but I have experimented with TheIsolator for my jekyll blog. Its simplicity appeals to me.
