lets say someone posts a nostr:npub12vkcxr0luzwp8e673v29eqjhrr7p9vqq8asav85swaepclllj09sylpugg link on x/twitter, the user clients the link reads it n continues scrolling, a pop up appears that says “join over x amount of people using nostr to escape censorship” or sum like that and then gives them the option to sign up or log in and at the very bottom it says something like “coming from x/twitter? Sign up” and the button directs them to a page where they put their username inside of and it checks if that username is available to use as well as it asks them if they’d like to populate the same profile from x/twitter to nostr, which will skip all the steps of setting up the profile, once they do that they’ll have a profile pic up, a bio and a username and maybe even the banner image as well.
