More Facebook Disasters

Beacon, the advertising delivery platform in Facebook, has a dark side. As it harvests your sales information, it can mate that with your friend lists and use that to target others. Fine, as long as your purchases are those that you want to share with friends.

Think that new commercial with the voice activated MP3 player in the car that gives up the embarrassing info that you have Michael Bolton in your artists. Except all your friends without your permission know you just bought MB's greatest hits. An alert -- hey, Dr. BS just purchased MB's greatest hits -- with the hope that your friends will want to join in with your trend.

More likely, things you don't want others to know are revealed. From the , the gift you just bought your significant other is outed. To the creepy, that the gift came from Frederick's, and perhaps you have a liking for French Maid outfits.

Remember, you volunteered for this when you signed up for the SNWs. Ooh la la.
