yes very. currently at ghost now for over two years. And would have hope them to take on nostr instead of activitypub as their new horizon.
email will be nice in order to reach that audience.
I need to revisit npub pro again to see what's new. I think I read you can filter the feeds now? a big drawback for me before was that very post show in your site, not just long reads.
will check it out again.
