Aardvark is a crowdsourcing platform for asking and answering questions, that was recently acquired by Google. When a question is received, Aardvark finds the perfect person to answer it by looking through your social connections, and others who have a knowledge of or an interest in the topic you’ve asked about. Although you can ask Aardvark anything, and most questions are answered within five minutes, popular topics include travel tips, product recommendations, local services, and restaurant suggestions.
