Tom Simonite:

A new app called Silent Circle tries to change that by encrypting calls, e-mails, and texts. It’s aimed at activists, companies, and individuals who fear they’re being spied on.

In other words: it’s aimed at me.

Think of this though, for all you spy lovers, this would be a way to finally have your own “secured line”. Thus allowing me to now say to people: “this line isn’t secure, I’ll call you back on a secure line”. Awesome.
