Following last week’s rollout of link stickers, Instagram is introducing a new sticker called “Add Yours.” The company describes it as a way to create public threads in Stories. It also notes it’s the first time it’s added a way for people to publicly participate in the format.

That’s because when you tap on the sticker the interface will display everyone who has contributed to the thread and you can view their Stories from there.Add Yours = a sticker that creates public threads in Stories 🤝With custom prompts and public responses, you can share the sticker and see who responds to it in their own Stories. pic.twitter.com/C9AXiFEo92— Instagram (@instagram) November 1, 2021The tool could help Instagram boost engagement at a time when it’s reportedly losing users, especially younger ones, to competing platforms lik
