“One of the major drawbacks of e-mail was that it is mostly insecure (i.e. delivered in plaintext) and unauthenticated... Thanks to the identity technology of the Social Web, she is now able to verify whether or not she is communicating with another user or not, and thanks to the identity and profile management in her browser, she even by default uses public key encryption to encrypt her messages and social media she sends to her friends if needed”
