Snapchat's (and now Facebook Poke's) main claim to fame is that it lets you send "self-destructing" image messages. Setting aside the debate about the uses of this beyond sexting, the key vulnerability in both apps is the built-in ability to take screenshots. Both take a reactive approach, where you're notified if the recipient took a screenshot, but can't really do anything about it.
