@DePemig for publishers you can think of a blog category as having its own atom feed or activitypub outbox. in my website's static site generator (hugo) i configure a taxonomy called "streams" which output to multiple formatseach rss channel item / atom feed entry / activitypub outbox activity / etc can be attributed to some author that doesn't have to be the actor you followed. this might cause some weirdness in tracking your "following", since you never followed the author themselves.
