I like this conversation, but bitcoin address reuse is encouraged to obfuscate your identity or association with UTXO's. In the case of Nostr or any social media the objectie is to associate an identity with messages.
Discussion
A success point of twitter was its ability to create anon accounts. We can think of identity management as many anon accounts that someone could prove they control "if" they want to.
Correct. The problem of nostr is exactly that there is only one identity, one key. If you move to another key, you have to start from scratch. PMs are resetter, followers need to migrate etc. In the long term, having your life tied to just one identity is dangerous.
But you could always prove you control this other identity by messaging from your original identity.
Not necessarily. You want to disclose to your friends and followers, but you may not want to disclose your identity with the whole world. We are just too used to surveillance to even realize that it's not needed.
well the beauty of what you are describing is the ability to use anon accounts but be able to prove to others that "you" identity of another account controls this other anon account where random strangers may not know this.
you could do this by generating a new nostr priv key and then messaging to followers you want to know proof that you control this other account.
