Snapchat's Shared Stories will let you collaborate with friends of friends
Snapchat has updated its Custom Stories feature to allow more people to participate. While the original version of the feature only gives you a way to add friends to view and contribute to your Stories, the new version calledallows the friends you add to add their own contacts. Say you're cooking and want your friends to add their cooking Stories, too — just add them to the group, so they can add more people, as well.
Like regular Stories, shared ones will only be visible for 24 hours before disappearing, but it doesn't have a chat component, probably because it's assumed that not all participants would know each other. The app will also use automatic language detection and other review tools to monitor additions and make sure they're all safe. Finally, you will get a notification if you've joined a Shared Story with someone you've blocked.
