Nerval's Lobster writes "Our lives online come with perils, whether from the NSA checking up on our digital communications, or the possibility of the wrong e-message going viral. Twitter, Facebook, Google, Instagram, and other social networks have collected all sorts of personal data about us, where we've been, what we're saying, what we like, and our friends. No wonder the idea of ephemeral messages — such as those sent via Snapchat and other services — is beginning to resonate, attracting lots of startups who want to service that very need. These creators of self-destructing message apps claim they don't care about monetization, and that their products are secure — but as so many apps from other startups have demonstrated, security is often a very porous thing, and government agencies are more than happy to fire off a warrant to see unread messages stored on a server. Lots of developers want to become the Snapchat (if it means they can take a multi-billion-dollar buyout), but in the case of vaporizing messages, they're tiptoeing into tricky territory."
