Google Buzz is under fire for violating the privacy of its gmail clients by making their email contact list into a public friends list on the new social media platform. "When Google introduced Buzz — its answer to Facebook and Twitter — it hoped to get the service off to a fast start. New users of Buzz, which was added to Gmail on Tuesday, found themselves with a ready-made network of friends automatically selected by the company based on the people that each user communicated with most frequently through Google’s e-mail and chat services. But what Google viewed as an obvious shortcut stirred up a beehive of angry critics. Many users bristled at what they considered an invasion of privacy, and they faulted the company for failing to ask permission before sharing a person’s Buzz contacts with a broad audience. For the last three days, Google has faced a firestorm of criticism on blogs and Web sites, and it has already been forced to alter some features of the service. E-mail, it turns out, can hold many secrets, from the names of personal physicians and illicit lovers to the identities of whistle-blowers and antigovernment activists. And Google, so recently a hero to many people for threatening to leave China after hacking attempts against the Gmail accounts of human rights activists, now finds itself being pilloried as a clumsy violator of privacy."
