Snapchat has never really impressed me and they deserve their public market drubbing. But this is really cool tech they have come up with. Extrapolate this to be used at any event where many people are present – concerts, speeches, sports, etc. Why is this important? Let tech companies come up with the tech, and then brands can use them. This is another cheap way in which small companies can use advanced tech to create interesting content. If I did events for my company or was involved in events, this is something I can get my audience to use to help promote me.
