Facebook Privacy issue won't die

This issue has been discussed on a few blogs so far, and I've finally understood what the hullaballoo is. I don't shop online, but if I did, I would be very peeved if that information was shared on my newsfeed. Why? Firstly, because I did not say they could share it.  And since they didn't ask me (via an opt in policy), they can't know that this is information I don't want to share with all the people on my friends list!

As Arrington says - Notifications won’t be enough for MoveOn and many users who are seriously pissed off at Facebook right now. Facebook’s best move is to make the new Beacon service opt-in only. But that reduces the value of the service to third parties who supply the information to Facebook, and get free links in return.

A classic case of the tension between marketing dollars and the user experience?
