Google announced they are now incorporating Google + posts and information directly in the search results.
Here is a picture:
Now, prior Google did show these types of information with Twitter results and even based on your Google Profile public links profile. Now, Google will show all the public posts that you or your friends made in the search results.
Remember, to experience this updated feature, you’ll need to be on Google+ and also make sure that you’re logged into your Google Account when you search. In addition, only public posts on Google+ are visible in search results. Private posts on Google+ aren't.
