I dont understand either, G+ is my primary social media, and once you actaully start using it, and circling people correctly, I have noticed I get much better search results.
for instance I am a big fan of Doctor who and Magic the gathering. because of that I have a lot of people in my circles that are also into the same things.
many of my searches on google relate to either of those things, and when google shows me that the following X people foudn the result third from the top useful, it saves me time because I know that will be the link I need.
also on the tab you might have it set up to search plus rather than google, if that is the case, your bad dude.
