What do you think? An invasion of privacy?
From what I can tell Google is now indexing wherever we are using one of their services so they can tailor ads and the like toward a more accurate and complete picture of us.
Under this new policy, a user with a Google account who signs into Google’s search, YouTube, Gmail and other applications is treated as the same individual across all of those services, and data may be shared between those services. Consumers may not opt out of this change, which goes into effect March 1.
