Nostr is currently a leaky ship with a lot of bad practices baked into the NIPS (external links to profile images LOL)

That being said, I think it is a great paradigm shift towards what is essentially a decentralized database query protocol. There's many cool applications that are waiting to be built!

There's also a lot of challenges yet to be solved with pubkey based identity. Like, how do you rotate private keys if your key is compromised? There's no password reset in ECDSA :-D

What an exciting future! Can't wait to build on top of it.
