Aardvark describes its service as "a way to find people, not web pages, that have specific information." After signing up, users can build up their contact list and choose topics that they're knowledgeable about so that the site directs appropriate questions from others to them. As of October 2009, Aardvark had 90,361 users, of whom 55.9% had asked or answered a question according to the company's own numbers.
Google declined to share financial terms of the deal but it is being reported that the search giant paid $50 million for the startup. Details regarding timeframes for the deal and the fate of Aardvark's technology and employees are still scarce at this point.
