Are you talking about Nostr or some client?

I agree with what you wrote, but this is not inherent to Nostr itself. All that critique mostly addresses client side of things here, except user base I guess. When you write about UI it doesn't make sense, since Nostr has no UI on it;s own 

 Most of them. The ui in the ecosystem is overall good. Yes these are client side issues because the clients are how people use the protocol. Clients are nostr.  

 Agree. The clients are Nostr. They represent the ecosystem.
