I just made a Mystics of NOSTR follow pack. It seems to have created some kind of NOSTR event that is visible to Amethyst users but not Primal, Damus, etc. on iOS it seems.

I don’t see anything on following.space other than follow buttons, the option to create a follow pack or edit one you already made, and a sort of “follow pack post feed” like setting X to a “community” instead of “For You” or to “Following”
