You can share your profile using a vanity URL if you are a Nostr Plebs member.
Your vanity URL will be
https://nostrplebs.com/s/name. Replace name with your own ID's name part and nostrplebs.com with another domain if you bought a name under another domain.
An example: https://nostrplebs.com/s/derekross
You can put the vanity URL on your profile in social media websites or send them to someone so they can follow you.
