Facebook is testing a new option that allows users to share posts to subscribers only for a limited amount of time before they appear as public. Options currently include 24 hours, 48 hours and 1 week.
This new option could be a good way of providing more value for subscribers, as well as incentifying followers to subscribe to access content before others
Users can now create posts with reminders on Instagram, which people can receive notifications for. This is a valuable feature for capturing interest in a physical event, merch launch or new music.
