Socialized Q&A websites are more like social networks, helping users solve their doubts in the form of communities. Social Q&A makes up for the instant search for implicit knowledge.

It presents the best answers to questions and comprehensive relevant knowledge through three major functions (following topics, following questions, and following all questions and answers of a user), and enables people to establish social relationships through information clustering.
