When you come across something in feed that inspires you — like a post from a friend raising money for a cause or a photo of a new design from your favorite brand — you can now quickly share that post as a sticker to your story for your friends and followers to see.
To share feed posts to stories:
Any post shared to a story will include a link back to the original post and include the original poster’s username.
Only posts from public Instagram accounts can be shared to stories. If you have a public account and would like to opt-out from letting people share your posts to stories, you can do so within Instagram’s settings.
I am starting to use the heck out of this new feature. Let me know what you guys think.
