Why it's crucial for social networks to make privacy obvious

In today's Science Daily: Many Online Social Networks Leak Personal Information To Tracking Sites, New Study Shows. Science Daily does an excellent job of explaining the technology; our usability studies show that users are acutely aware of being "tracked" in some way. This is as true of the 13-year-old "digital native" as it is of older late-adopters. If you want people to adopt your social network, you MUST declare privacy policies - particularly at interaction points such as registration fields and profile set-up forms.Kudos as always to Science Daily.
