Going on a whim, but I feel that mass perception is in Snapchat's favor here. The public doesn't explicitly trust Facebook with all of their stuff, despite putting just about everything online - but this is entirely different. The nature of the disappearing messages is inherently very private, something people don't associate Facebook with at all. I've got a little selection bias, but none of my friends with Snapchat have heard of Poke, let alone use it. It may not be here to stay forever, but I don't think FB can kill it itself. A third party with better design, maybe.
