Portable identities are the biggest reason why I use #Nostr.
Before I started using Nostr, I was using #Mastodon, but I was really annoyed that I couldn’t just move to a new instance.
Well, Mastodon is a bit complicated, because it is technically possible to move from an instance to some other instances (not all, it depends on the individual instance), but you will lose ALL of your content (posts and replies) which makes moving between instances completely useless.
Why would I move instance if I lose all my stuff?
With Nostr, there is no reason to worry about this. You just have your keypair and can use any client you want. You can even build your own.
Coolest part is, you keep all your stuff like your posts/notes when using your Nostr identity on different clients.
