Most of not all of the new Nostriches in instructions are Damus users. This is because Damus encourages you to make your first note with that hashtag.

Imagine all of the others that are alone, cold, and scared, that joined Nostr on Primal, Amethyst, or Nostur. They're talking to the void right now. 😩

You can easily find them by adding the welcome.nostr.wine relay to your relay list and configuring your app to use that relay for a dedicated feed. Many apps support this one way or another.
