Make privacy even better, & transparently so. I don't think hardly anyone knows exactly where Nostr is completely private and where it's sorta private. It may be the best private communications network mankind has ever made, but it seems there has been zero public education on what it's limits are. At the very least I'd like to see apps give you a link at the time of posting explaining exactly what these limits are... So you know if the fedcoats are going to show up at your door or not when you say something risky, for instance.
I don’t think of Nostr as a privacy tool. I consider it more a censorship resistant speech tool. So I can say what I want and be pretty sure anyone could read it, but I don’t think it does a great job at helping me hide who I am… unless I create some sort of nym/anon account?
The two tools often overlap... Speech in oppressive countries isn't ever free.
Thinking about things like VPNs/IP address hiding from relays?
TOR is the best they have in that scenario but would you literally bet your life on it? They need Nostr to do more.
