This document discusses privacy and metadata in online communications. It presents a spectrum of privacy for different types of personal information, from most private like passwords to least private like public information. It then introduces some privacy-forward services like Crypt.info that aim to provide secure messaging without metadata. Crypt.info is described as the "anti-email" that allows anonymous and encrypted communication without identifying information about senders or receivers.
