I'm not sure about this. Users will read about Nostr and end up trying something like Nostrudel, Primal, Damus, or Amethyst. If they encounter bad UX, they’ll bounce and likely won’t come back. If we don’t build a solid experience today, there won’t be enough users willing to try all of the “micro apps” for Nostr. At the very least, we need a functional, pleasant, easy-to-use Twitter clone. Just look at ActivityPub software: as much as I like Peertube, Lemmy, Pixelfeed, etc., it’s the plain, “boring” Mastodon that really brings users into the ecosystem.
As for downloading multiple micro apps, like a “Signer,” “Local Relay,” and “Notification Receiver” just to use “Twitterst,” “TickTockstr,” or “Spotifiestr”… I don’t think that’s going to fly with anyone outside the dev community. Bundle or no bundle, there’s very little incentive for the average person to jump through all these hoops. But, as always, I’m happy to be proven wrong.
