the social graph (which Mark Zuckerberg defines as the network of connections between people) reached a new stage of legitimacy or recognition today with a post by Tim Berners-Lee, who invented the World Wide Web in 1989.

In the post, he broadens the scope of the social graph, linking it to the Semantic Web, coming up with the Giant Global Graph. Nova Spivack of semantic Web startup Radar Networks has defined the semantic graph as “connecting people, places, companies, products, Web pages, videos, photos and turning it into semantic Web content.”
