Nice to see a blogpost on the Mastodon blog about implementing a basic ActivityPub server blog.joinmastodon.org/2018/06/

(Though technically webfinger isn't needed for activitypub, but it is for mastodon interop!)

@cwebber I'm curious how subscribing between different AP server implementations is going to work UX-wise. Mastodon, Pleroma and peertube all work with the user @ domain webfinger scheme, but what identifiers shall be used for implementations lacking webfinger?

@schmittlauch @cwebber Or just click someone's username in a toot. That's also handled without any acct: URL involved. Basically WebFinger is only necessary for the case where you want to look someone up by @ identifier, and maybe even only for the case where you want to do that, and the server didn't already see a message from them.
