Allow me to give you concrete cases. I was looking for a good raspberry pi breakout board so I can use the GPIO without concern that a bad soldering job would lead to a dead board. I type this in and I see those little people and +1 notifications for some products and blog posts and not others. I also see promoted images from a friend who just installed one.
I have a fairly good idea about the authenticity and trustworthiness of these people, and so the search results have helpfully incorporated this data and helped shape my purchasing process.
Now, I have made it a point to cultivate relationships with people in this space that are also G+ users, so it isn't "free", but it pays off pretty handsomely in cases like this.

Is that not a clear enough value proposition?
