I don't actually use Mastodon anymore, but am tempted to try this out. It would be cool to have comments on the blog, even if just for the process of going through the motions and gaining a bit deeper understanding of ActivityPub. 

This has the potential to become a rabbit hole for me though, as I'm sure I'll have to set up my own server and all that entails. I've been enjoying Heroku as a hosting platform so I bet it won't be too bad to set up (famous last words).
