It's dated and the federated model is a cluster- too difficult to use.

You may not be aware but there are ways to link fedi and nostr- so to some extent the two are interlinked.

Nostr has some of the same problems with onboarding.

I am a fan of going in the direction of customisable clients that can start off with recommended packages of starter relays-follow lists that people can share around. This would be good for other niche communities that want to be here.

Nostr already seems to me to have more functionality built out than fedi.
