I've been doing it on You Now, a mobile app and web live-streaming app that's a hit with teens.
On its popular #sleepingsquad hashtag, I can see about 20 sleeping teens at any given time.
(It usually seems around 50-plus people are broadcasting in the hashtag, but a lot of them are in complete darkness, so you can't actually see anything.
Because, you know, they're sleeping.)Some teens sleep with light music on. And some, eerily, have the distinctive soft breathing sounds of sleep. I have asked other teens (or younger — I talked with kids as young as 10) why they use You Now, a real-time video broadcasting app. Do adults really ever have a better answer than "I was bored" for anything we do?
Just as spoken words only hang in the air long enough for ears to hear them, these images last just long enough to be seen (or more accurately, for 24 hours) and then they disappear.
