Now would probably be a good time to talk about the elephant in the room: Mastodon. I [like to say](https://social.exozy.me/@a/109712197207851220) that the reference implementation and test suite for ActivityPub is Mastodon. Why? Because there's no official reference implementation and the official test suite has been unmaintained for years. Mastodon is so large that everyone prioritizes compatibility with it and doing things the Mastodon way, such as using WebFinger and HTTP signatures, which aren't even in the ActivityPub spec.
Wait a minute, WebWhat? If you think about it, our current implementation is not-exactly user friendly.

Mastodon's solution is to use the WebFinger standard. You get a nice, short cozy username like `@billiam@centipete.exozy.me`, but internally, it's gotta be translated to the long URL version. To do that, simply fetch `https://centipete.exozy.me/.well-known/webfinger?resource=acct:billiam@centipete.exozy.me`, and it'll hand you some JSON:
