Next up: social search engines.
Once you tell Delver who you are, it builds your social graph by itself. It correlates your identities across sites like MySpace, LinkedIn, Flickr, Facebook, Digg, and more, and creates a list of who your friends are. It also layers in a list of your friends of friends. Then, when you search for something, it gives precedence to content and links from your friends and their friends. So if you're looking for an Italian restaurant recommendation in New York, you'll get results from people you know, or people your friends vouch for. Delver CEO Liad Agmon clearly believes that online content from people you know is more valuable than generic Google results. He says, "The Web is no longer just a collection of documents. It's made up of microcontributions."
