Whenever a user publicly shares a link on Google+, an annotation will show up under that link when it appears in a friendís search results. For example, if I share a Mashable article about Google+ eliminating pseudonyms publicly on my Google+ page, users who have added me to their circles will see a note that I shared that link if they stumble upon it in Google Search. [mashable.com...]
Today, we're including public Google+ posts as well. So if youíre signed into your Google Account, your search results may start including posts shared publicly by people youíre connected to on Google+.
I search with my google account logged OUT more often than on since I need to see what Jane and John Doe see, not stuff targeted just for me.
