No. It's the other way round.

Nostr doesn't need more writers or webpages. Existing writers and webpages need Nostr.

Writers can benefit from Nostr’s architecture to secure their content against censorship and downtime, while existing webpages should evolve into Nostr clients to enhance their reliability and reach.

Nostr doesn't need its own Nostr writers or Nostr musicians or Nostr streamers or Nostr wiki page writers, we're not a walled garden, Nostr is just an infrastructure to be used by all.
