Substack on-ramp is here already: migrate.nostr.com

Would be nice to have a great Twitter migration tool as well.

- https://fedifinder.glitch.me/ was helpful last year scanning Twitter for addresses people had in their bios for Mastodon.

- It could also clean the Twitter archive, download the pics in OG format (since they are not in the zip-file birdsite gives). The latter part is here already: https://github.com/timhutton/twitter-archive-parser

And then the rest: Instagram, Mastodon, Linkedin 🤣 etc.
