I agree, I just hope the average snapchat user realizes that there's no guarantee the pictures they're sending can be archived forever (especially the younger users).

I never used the app though, and I just tried to go to their website to see how they communicate on this issue just to discover that snapchat.com doesn't contain a single description of the service. There's just a silly video on the frontpage (turtle fights? I'm not sure about the ethics of that) and links to download the app. It's crazy that something so new is already popular enough that they don't even need to explain what it is anymore.

That being said on both apple's and google's app stores the description of the app mentions that the user can make a screenshot and save the picture, so at least they don't try to hide this limitation.
