“If you’re not paying for something, you’re not the customer; you’re the product being sold.” —blue_beetle, Metafilter discussion.
Google started off the new year by announcing that they will be changing their privacy policies so that they can create more detailed profiles of their users. Starting March 1st, 2012, Google will combine information from user’s Gmail, Google Search history, YouTube, and other services. Prior to this change, Google profiled their users, but restricted the profile data use to the service from which the data was collected.
