This got me looking into what it would take to start publishing my own static file GitHub Pages-based blog using ActivityPub. It's something I've wanted to look into for a while.
It looks like at the very least ActivityPub requires a host that responds to POST requests, so GitHub Pages is out. But I found a blog post of someone using serverless functions to handle the ActivityPub part of their static site. I might try that out.
Does anyone here happen to have any experience with setting up ActivityPub for static pages? I'd be interested to know how you set things up.
