Yeah, its good to think along those lines in terms of how adoption can grow and how network effects can accelerate through things like contact discovery and social graph effects. Those mechanisms definitely helped platforms like LinkedIn and others scale massively. At the same time though, I think it’s important to take stock of how far Nostr has already come organically and grassroots, without those kinds of aggressive growth tools. Considering it’s still early and largely driven by word of mouth, open-source builders and aligned communities, the level of adoption and engagement already is actually pretty impressive and probably a strong foundation to build from. In some ways that slower, more intentional growth may end up being one of its strengths rather than a weakness.

Didn’t linked in send an email to everyone in your contact list?

Nostr clients should implement a privacy preserving version of this like vexl has

We can send zaps 12 different ways but we can't automatically add people from our contact lists

already been researching this via private set intersection. Should ask how vexl is doing it

This is backwards, Npubs are the identity layer. "Share contacts" is a base feature of nostr via Follow sets kind. It's making an Npub that is the initialization barrier. Very likely more time needs spend on the onboarding flow to backup a new Nsec securely for easy transfer to new apps.
