The feature suggests your name or your friends' names whenever you upload a new picture. It takes a step out of the process for tagging friends during photo-sharing. Some users love it, but privacy watchdogs are bothered by the idea of software analyzing faces and identifying them in other people's pictures. Privacy laws are much tighter in Europe, so what may not be illegal in the United States could be illegal there.
Palo Alto-based Facebook is apologizing, the company says it could have handled the launch of the feature a lot better.
