I think there is a reasonable framing of nostr as the glue to unify all public messages. I would get more value from nostr if I could read more of what I want with it even if those who create such messages are not yet on nostr natively.

yeah, 100% -- it's a value-add for people who are already in nostr, but people not in nostr won't come to nostr just because they can *also* access some content that is available where they already inhabit
e.g. a hacker news user won't flock to nostr because hacker news content is on nostr
but for someone that is already in nostr, having hacker-news-curated content here might be useful
also, it gives people like us who *are on nostr* more content that we can discuss here
