Yes! I noticed this again when Pablo released Nutsack and it just works with what I have been building for 8 months

I'd rather call that portability. While there are some significant successes, and noticably over silos, nostr struggles to fully interoperate with itself. Something as simple as replies work (or dont work) differently in most clients. And nostr has almost no interop with the wider web. So much more work to be done here, that is not getting done.
