Close Friends
An Instagram feature for sharing stories (and now posts) only to a hand-picked "close friends" list instead of all followers. Marked with a green ring. It provides an intimate channel within the public account.
Mechanic: you build a list and choose at posting time whether a story goes to everyone or only Close Friends; recipients see a green marker and know they're in the inner circle. Use case: uncensored content, personal updates, jokes not meant for the whole following — roughly the same need as a finsta, but without a separate account. It's also used for status ("who's on your green list?") and by creators for exclusive content. Part of the platforms' answer to the trend that people want to share to smaller, trusted groups.
