That's one of the common complaints of snapchat. I'd bet most people that even use snapchat don't even know how to get to this feature in the app. It was released some time last year without much press (I think they did a self-snap story about it) and even took me a couple tries to figure out how to get there when I knew about it. There's literally no way of knowing that view exists without just knowing it or accidentally triggering it, and I didn't even know there was a web interface for it.
