I guess subdomains are possible. And those would probably just redirect, the structure and costs meaning they probably don't actually represent an app view or PDS or whatever?

AP uses the same URLs you would be able to load in a web browser because it's a web spec. So for example you are https://liberal.city/users/wjmaggos as far as AP is concerned. You *could* be https://wjmaggos.liberal.city/ but mastodon doesn't currently support that.

I don't understand your equivalent example.

as I understand it, AP would use @alice@example.com while AT would use alice.example.com. then bob and carol etc.

AP would have one server for all the users, both data store and how they post/read etc. would AT require a different PDS for data for each account and then have most people still use bluesky or maybe blacksky for posting/reading etc? I know they could run their own app view but the cost would be much higher than an AP server etc.

- atproto requires a DNS name (and the TXT record points to a DID which points to a PDS)
- activitypub requires a URI (which in most cases you just HTTP GET directly, optionally following HTTP redirects)
- you could satisfy both by assigning subdomains or letting users bring their own domain

so alice.social.example and https://alice.social.example could be used ~equivalently, but https:// social.example/alice wouldn't work as an atproto identity.
