No, it's not that they are guaranteed to disappear. It's that there is no expectation for them to last. It is an ephemeral image that doesn't need to be saved or managed or taken with the gravitas that living in your camera roll or being posted for the rest of time has.
taking the perspective of the receiver is hard to justify as well. I mean really deleting a mms or just disabling it in any of the messaging services really is not that hard.
And yet, here we are with snapchat being hugely successful. Maybe you just don't understand what makes a product like this successful, and why things that are "not that hard" may be something that literally nobody does for a certain reason because they are hard enough.
im not saying its not hard and im not saying I dont' understand it, but to claim its something more than just the fad and brand is what im questioning.
