You’ll see a new story ring at the top of Explore filled with stories happening near you. These stories come from people who have used location stickers on their stories. You can also search for any location around the world, and you’ll see a story ring for that place at the top of the location page.
Hashtag stories are also going to begin appearing on Explore.
When you search for a hashtag, you may see a story ring at the top of the page filled with stories using that hashtag.
Instagram notes that adding a location sticker or hashtag to your story may get you included in the larger story. If your story is added you'll see a line at the top of your stories viewer list showing how many people saw it in the larger story. If you want to use a location or hashtag sticker but don’t want your story to appear on Explore, tap the X on your stories viewer list.
You can download Instagram from the App Store for free.
