The latest Google+ update now lets users specifically search through their friends' likes and +1’s to find things that they might be interested in.
How the Google+ update works is by letting web browser users access what people in their circles have liked or given a +1. The likes and +1s can then be searched through, like a standard search, but the results are niched to only show things people you know have liked. Popular posts are then highlighted onto the users Google+ main page. In return, the user’s own popular searched posts will show up on friends’ Google+ profiles. This addition will work well with the recent update that added the +1 action to show up directly over content posts. Users will see the Google+ update as a great way to exchange and interact with the interests of friends.
