It's impressive just how quickly Instagram can roll out new competitive features. For those who've already found great value in their photo zooming and the addition of stories (which 100 million people have now used), there's a new trick up the social media service's sleeve, out today: live videos. Now, users can stream live experiences directly through the stories section. As with images in the stories section, videos (which can be up to an hour long) disappear in time. Taking a page out of Snapchat's playback, Instagram also introduced a disappearing photo and video feature for direct messages. In adopting what's been successful with their peers, Instagram continues to solidify its importance as a go-to app.
