The relationship to bitcoin besides being created by bitcoiners is that it uses Schnorr Signatures for the secp256k1 curve - the same curve as bitcoin.

A Nostr account is identified by a public key, you follow accounts by following public keys and the ability to post as an account is controlled by the corresponding private key.

https://www.nostr.directory

This tool lets you broadcast your pub key on twitter using a specified format, and the app will add you to the directory, and you can use it to find others that have also done that.

Also, if you go to https://snort.social/new, you can enter your twitter handle, and it will find everyone from you're twitter follows that you're not already following and let you sign up to follow them all.

Does this mean I could use a bitcoin hardware wallet to store my nostr keys and sign my posts?

Yes, it does assume someone writes a client that enables this.
