Overheard: Beacon alerts may be controversial, but they’re the future of advertising

Facebook rejected the claims [of violating privacy] and said that its users are given two chances to opt out of sending a Beacon alert to their friends. It claimed, “Information is shared with a small selection of a user’s trusted network of friends, not publicly on the Web or with all Facebook users They also are given multiple ways to choose not to share information from a participating site, both on that site and on Facebook.”
