Facebook keeps squashing some very specific personal privacies. A feature to recognize faces might be great on a personal desktop application like iPhoto, but not on a web app. This could mean that they are trying harder and harder to be the new CIA - data mining for personal data. This goes as far as forcing people to tag others' photos without their consent. I know for a fact people try to untag themselves from photographs; why force them to be tagged? Information wants to be free, but only when you let it be: not forced.
