Back in the early days of the World Wide Web, the internet functioned like a masquerade ball. You could log on, express your strangest thoughts or deepest fears, and it was possible that no one would ever know your real name. Indecipherable handles, avatars, and pseudonyms shrouded our identities. Then Facebook and Twitter came along, ushering in a new identity-based era of online social networking. Who we are as individuals became a matter of how we presented ourselves in status updates, tweets and Instagrams. Today, your online identity is really only as good as your last post.
