I partly agree, but I do think DHTs are neat, and I'm glad someone's using them for something equivalent to "relay discovery." I'd kind of like to build out something similar to that for nostr.
I don't like that messages are not signed, that seems like a recipe for disaster, but I think it's important to John because if you have to sign every message, then you need to keep a key in a "hot wallet" or face the annoyance of breaking out your "cold wallet" whenever you want to post something. And I think John regards *that* as a recipe for disaster.
Anyway, I'm glad there are options!
