@jenniferplusplus @tess @smallcircles @cheddarcrisp I think that’s how Mastodon and Pixelfed are implementing groups instead, so actors can see/follow/address a group/collection, comparable to mailings lists (or usenet).

A circle in our case is private to its creator, who alone can see their circles and who’s in them, and can address a circle when posting, like defining a group/list in your address book, and addressing it as BCC in an email.
