Today we’re doing a little bit more to bring you all the goodness of Google, plus the opinions of the people you care about. As always, we want to help you find the most relevant answers among the billions of interconnected pages on the web. But relevance isn’t just about pages—it’s also about relationships. That’s why we introduced Google Social Search in 2009, and why we’ve made a number of improvements since then. Today we’re taking another step forward—enabling you to get even more information from the people that matter to you, whether they’re publishing on YouTube, Flickr or their own blog or website.
