Flawed audience measurement firm Nielsen is shutting down its social networking site Hey, Nielsen after more than a year of getting members to reveal personal information and viewing habits for free. Indeed, Nielsen is shuttering the one service that's both cost-effective and informative, so they can focus on more flawed, but wildly more profitable services. "Asked by one member, screen-named Cookieduster, if the members of Hey! Nielsen who selflessly volunteered their own personal information, preferences and insights for more than a year weren't 'owed a summary report of how our input was used (what research projects and for whom?) and what it might have meant,' Nielsen replied curtly, 'We cannot share any client details as this info is confidential. Your feedback has been very useful and we appreciate your participation.'" [MediaPost]
