Facebook sued for scanning users' messages

Regardless of the merits or the outcome of this case, it's fair to say we Facebook users are openly inviting the vampire-marketers into our hearths and homes. A bargain with the Devil for our 'free' social medium. To sling a little economics jargon, network goods can be a bitch. (Since everyone is using Facebook, it's not easy to find a substitute with as many people we know.)
