The "+1" button you see on many websites is a simple way to give something your stamp of approval. But unless you share your +1's on your Google+ profile or your friends spot them in search results, no one will ever really know that you cared about a particular site or story.
Now worries though! Google's got a simple solution for this problem: Soon the search engine giant will start showing your profile picture and name when a friend of yours hovers over a +1 button you've clicked.
This feature has been rolled out to folks using the Google+ Platform Preview, but the rest of us should be seeing it soon as well.
