Privacy advocate and executive director of the Center for Digital Democracy Jeffrey Chester wants you to worry about Google's plans to allow other companies to track user behavior through its advertising platform. "Google has now sanctioned behavioral targeting on its network, and users have no idea what the implications are," Chester told PC World. He said these third parties — ad agencies and ad networks, mostly — "are using the Google network, and you don't even know about it." Boogity boogity boo! Don't let Chester scare you. On the Internet, your privacy is an illusion and you know that. PC World just likes to remind you — today's story is the magazine's ninth to feature Jeffrey Chester since November — because it helps pays the bills. Don't believe us?
