This is the decentralized part. You can connect to multiple relays and have your notes published there. You can run your own relay and have your notes published there as well. The relays can do whatever the owners of those relays want except alter your notes (because of signature).

Do relays only broadcast notes? Does a relay every copy and save a note broadcast from another relay?
Relays do not talk to each other. They are their own separate entities. All relays do are accept and save notes and let you run queries on those notes.
I’m sure someone somewhere has coded a relay to clone data to another relay but that’s not part of the protocol spec to do.
I recently started running a relay and right now it has a copy of my notes (including this one I am about to send). It does not take in any notes of your responses unless you connect to my relay.
Cool, this is very helpful. Are relays networked at all? Or am I only seeing notes from people connected to the same relay? I think I’m only connected to one relay right now.
Clients connect to relays and publish notes. You pull down notes from other users. So yeah what you’re seeing is from people connected to the same relays.
Not sure what client you’re on, most seem to add a handful at least to help bootstrap user experience for people. I think I have 10-15 I’m on right now.
