There's more. Friends can respond to question stickers using Instagram's music library, so you can ask for on-the-spot song recommendations. And with New Year's coming up, Instagram is appropriately introducing countdown stickers to Stories to build up hype for events. You can use the sticker any time before the countdown is over, and others can follow or share a countdown to get an alert when it's over.

Most of the features are available on both Android and iOS today. You'll have to be patient if you're an Android streamer, though. While both Android and iOS users can create and participate in live Q&As, only iOS users can share mid-stream photos and videos right now (Android users have to be content with view them).
