Oddbean new post about login | logout There is a project that has not been updated since last year but its close. I know there are wordpress plugins for posting. https://github.com/chakany/nblog also I know @brugeman does some stuff with ghost on npub pro mabey they can help.
There is tool for importing stuff from Ghost at https://npub.pro/import-ghost but not for synching in real time. Not sure if full copying would be a great idea, but maybe auto-sharing a link on nostr would make sense.
