I think the nostr folk that are curious want to know:
- can we use some of that somewhere in our systems?
- can it help somehow for privacy related issues?
- etc...
Nobody is going to migrate just because you say: here, look, our tech is better!

As for me the idea of decentralized DNS, if it works for usual web dev, we can make it transparent for the user, and we can fork all your stuff and hack on it without the system breaking from all sides. It's a more important than nostr. But massive "if" there.
