Dear fediverse: appreciate the irony of asking for this, particularly on Mastodon: if you have come across any very good series or explainers on YouTube explaining how activitypub works, would you leave a comment in this thread?

I’m looking for videos, not written docs and specs. I’d prefer peertube links, sure, but I’ve yet to find any hosted peertube-as-a-service to recommend, and I do not want to be that guy telling everyone to self host all their own stuff.
