"Just recently, Google updated its terms of use and privacy policy. The goal was to allow Google to use your name and public photo in "Shared Endorsements." In plain English, it wants to use you in ads. So, if you like or "+1" something on Google+, for example, Google can show your friends that you recommend it if it pops up their searches. I'm sure Google can expand that in the future to the channels you subscribe to on YouTube or music and apps you buy in Google Play." - Harold
