@indirection @thegibson Unless you run your own instance, you’re publishing it on the outbox of someone else’s computer, which is functionally equivalent to sending your email to a public mailing list. So, that’s how email does it. What you can’t do the Fediverse is sign messages. Reblogs just kind of trust on faith that it came from whom you said it did. So PGP is the killer app for email that nobody knows about.
