Today, Google changes forever: The company is consolidating 60 of its 70 privacy policies, which will allow user account information to be exchanged between all of its products. That means that YouTube, Google Docs, Gmail, Google Plus and more can begin to communicate with each other and leverage data between each other. Someone's Blogger posts may affect their Google searches; Google Plus links may affect YouTube suggestions; information will flow seamlessly between all of the popular enterprises that Google owns. In essence, Google will have a much more complete idea of who each of its users are.
