When I post, how to then share? I assume there is a generated link somewhere. I don't really get the ActivityPub part. Are there people subscribed to distbin like it's a user? Well let's see. Can one create a distbin 'user' which people can subscribe to, send messages to? I don't see that in the options below. Looking at the "post via API" it seems there is no user and no kind of federation. There is no one to subscribe to. Hmmm, I don't get it.
