The difference between microblogging platforms and blogging platforms is that microblogging platforms make it easier for users to start posting and engaging with eachother. The difference between ActivityPub and traditional microblogging platforms is that ActivityPub facilitates communication between users of their choice of federated instances. The difference between Nostr and ActivityPub is that Nostr takes the ownership of its accounts away from the hosts of their posts. Don't get me wrong, not all of those platforms provide strict improvements, but I believe those are the essential changes that justify people using a new sort of platform. Do you see any issues with how I've characterized the essential differences between these platforms? Can you articulate the difference between Nostr and Pubky in a similar way? I would really appreciate hearing your thought process. I don't get to talk with many people who advocate for Pubky.
