How in the world does that work?  I&#x27;m too old to have caught that wave, but I have a younger sister, and it&#x27;s not like the snaps her friends send her go poof into the ether if her phone isn&#x27;t on the network when they are sent.  They&#x27;ve got to get queued up in storage on a server somewhere, they&#x27;ve got to get sent to her phone, and I assume, checksummed to make sure they didn&#x27;t get corrupted in delivery, possibly resent?<p>I mean, I hope SnapChat isn&#x27;t keeping photos, or else they&#x27;d be sitting on one of the largest collections of child porn in the world...
