I know that @mammoth is promoting their #SmartLists, which seem to be 1) public lists curated by select users 2) but which are strictly controlled by the app developer and 3) probably have to get permission from the listed users.
This is only made necessary because the main #Mastodon project refuses to add a subscribe-only lists feature (whether public or private) because Twitter’s implementation led to abuse.
