The Verge has a new article about ActivityPub. And it's pretty damn good: https://www.theverge.com/2023/4/20/23689570/activitypub-protocol-standard-social-network
There's a number of quotes from me in there. I enjoyed being interviewed for this: David Pierce was a very thoughtful interviewer.
I have more comments than that, but I'll put them in a followup in this thread. In the meanwhile, go read the piece. It's nice to read some well informed journalism.
