Update: Google has officially announced that the feature has gone live across Google.com!
Google likes to experiment with upcoming features of its products and a reader seems to have spotted a new one. Thanks to a new feature that Google has deployed into its Google Search page, users are now notified when it is the birthday of one of the people in their Google+ circles. A 9to5Google tipster showed us the new feature this evening, where Google displayed in the Google Search notification window that it was his friend’s birthday. Google also provided a “Say happy birthday” button that allowed our tipster to write a witty message on his friend’s profile for the world to see. How Facebook like! Check out a screenshot of the pop-up below:
