Except that you are not - if I talk with somebody for real, at least I know somebody listened to what I say (OK, or at least pretended to listen). Seems as if I could go through the effort to snap something and it would disappear before anybody sees it.<p>Does it also play on that basic human condition of not wanting to see options go away, so you frantically click through your friend&#x27;s stories for fear of missing anything? I could imagine how that would get users hooked, but I wouldn&#x27;t consider it a good thing.
