Nostr still has a lot to work on like metadata leak. For example DMs are private but anyone can still see who you are talking to and when. Also your IP is broadcasted to relays.
Would be cool if Monero community forked nostr and fixed both those things (Maybe thru CCS?). Probably a big task. I'm not a coder either.
I think Nostr already has a NIP or two to potentially address the DM metadata thing.
