Nostr has already begun to develop silos just like the various chat ecosystems...
This is why people still use SMS btw, they can actually talk to everyone with a mobile.
Part 3 from the note below is what I'm working on now. That's what Aedile and nostr:npub1qdjn8j4gwgmkj3k5un775nq6q3q7mguv5tvajstmkdsqdja2havq03fqm7's noscrypt are going to be: the foundation.
It's not just for our benefit, either. The project is by plebs, for plebs. Our code will be open-sourced and designed with reuse in mind. So even if it takes a while for our product to take shape, we're working to contribute to the broader Nostr dev community along the way.
