Anatomy of a Large-Scale Social Search Engine
...while trust in a traditional search engine is based on authority, in a social search engine like Aardvark, trust is based on intimacy. We describe how these considerations inform the architecture, algorithms, and user interface of Aardvark, and how they are reflected in the behavior of Aardvark users.

Aardvark are built on top of the existing communication channels that people use to ask questions to their friends: IM, email, SMS, iPhone, Twitter, and Web-based messaging.
