When Facebook fails, everybody hears about it -- we like to call it 'social sharing.' Here are some of its biggest failures
The Like button and "instant personalization"
In April 2010, Facebook rolled out the Like button and "instant personalization." Like Beacon, these services shared your information with "trusted" third-party sites, such as Pandora and Yelp, and broadcast your "likes" on third-party sites such as Huffington Post -- again, without asking or telling. The Facebook faithful reacted in predictable fashion, as did the U.S. Congress -- calling upon Facebook to explain and/or take back its changes. After weeks of stonewalling, the social network introduced simplified privacy controls, including a way to turn off instant personalization.
