Now normally Stories are viewable for a maximum of 24 hours after which they get deleted automatically. Stories Highlights lets your, well, stories be viewable even after 24 hours so if you have announcements or news and people missed out, they can simply visit your profile to view your Highlights.
If you're hosting an event or something, you can use Highlights to summarise the entire show, and users can visit your profile to recap what happened.
What about you? Have you archived your past Stories as highlights? How would you use Highlights in your business profile?
