Facebook pulls back on Beacon

It’s a new service that alerts your Facebook friends (via the news feed) when you buy something on sites like Travelocity, Fandango and Overstock, but after 50,000 Facebook members signed a petition dissing the new service over privacy concerns, Facebook now asks if users want to participate. “Beacon crosses the line to being Big Brother,” said Charlene Li, an analyst at Forrester Research, “It’s a very, very thin line.”
