"Google knows a lot, both about its users and about the internet in general. Today, the team in Mountain View has found a new way to share more of its vast knowledge of the web with us by providing background info on sites that show up in search results. You see, site information is gleaned from Google's Knowledge Graph, and for every site we've checked thus far, that means the data's coming from Wikipedia -- so don't go thinking that this new cursory background check is 100-percent accurate. Google's not providing the extra info about all sites, either, just those that are \"widely recognized as notable online\" according to the company's blog post announcing the new capability. Still, it's a nifty addition that should give netizens some peace of mind before clicking search-provided links, and Google's promising that as the Knowledge Graph grows, so too will the amount of information this new feature can provide."^^<http://www.w3.org/2001/XMLSchema#string>
