Nostr addresses aren't the final solution for the problem of human readable names since ICANN ultimately controls nostrplebs.com or whatever regular domain name.

BitDNS (ie. Namecoin) names are a perfect fit for Nostr. They're lightweight, ridiculously censorship-resistant, easily managed and can be maintained with Bitcoin Lightning payments.

We have integrated BitDNS for our Nostr client, Nymble, and the app will be available in the next couple of days. If you follow, I'll send you an update to try once it's released.
