It doesn't look like Instagram will stop lifting features from Snapchat anytime soon. Today it's the addition of stickers in Instagram Stories (a feature which itself was a direct Snapchat copy) on iOS and Android. You'll be able to add stickers for things like the weather, your current location and the time in photos and videos that appear in your story. Yes, it's not exactly groundbreaking stuff, but it's the sort of fun and irreverent thing that's made Snapchat more appealing to younger folks. Instagram (and Facebook) just want in on that action.
