Google introduced a facial recognition feature for its Google+ social network. So far, it has been fairly well received—in stark contrast to a similar feature Facebook launched a few months ago. The main difference between the two? Google asked permission.

Both the Google+ and Facebook facial recognition features are designed to automate identifying people in photos to make it easier to tag them. Ostensibly, it will keep people more connected, drive interaction, and improve the social networking experience overall. That is, unless it is viewed as a creepy invasion of privacy.
