Facebook’s new aggressive ad program, Beacon, is undergoing some changes because of pressure from its users and advocacy groups like MoveOn.org. Originally Beacon alerted your friends if you purchased something from participating sites, unless you took action to disable it, now Beacon has to be enabled by the user before it sends out alerts. The changes also come from huge advertisers such as Coca-Cola who are severing their ties with Beacon due to all the negative press. This doesn’t mean that there aren’t still privacy issues with Facebook.
