Different follow lists for different purposes is like having different keypairs but without the friction of having to change between them. On Amethyst it would be 2 presses instead of 5 possibly. Instead of Follows and global you'd have your custom feed you have named for yourself. For me it would be "Nostr devs only" and "Nostr devs + bitcoin people". I've tried to solve the information flood problem by having two keypairs with little success.
