Of all the Facebook-owned apps that copied Snapchat’s Stories feature, Instagram Stories are the only one that actually caught on, and the company has been adding new stickers and features to Instagram Stories to keep them interesting and give users more ways of interacting with their followers, and sharing moments from their lives with them.
This feature can come in handy if you’re trying to plan out something like a group vacation, or a trip out of town with your friends and family – it will automatically let you know who all are interested in joining the trip anyway (because only those people will request to join the chat, most probably), and you can then proceed with discussions for the trip, or whatever else it is you’re trying to discuss.
