[Objective] This paper explores the development of social Question and Answer studies. [Coverage] We used Google Scholar and CNKI to search literatures with the keywords “Social Q&A”. We then obtained a total of 77 representative literatures on social Q&A in conjunction with topic screening, intensive reading and retrospective method. [Methods] First, we introduced the development and early research on social Q&A. Then, we surveyed the latest social Q&A studies. [Results] At present, the researches on social Q&A focuses on four aspects, including questions, answers, users and platforms. [Limitations] More research is needed to thoroughly discuss each research’s topic. [Conclusions] Based on the current research, we offer some suggestions on future social Q&A studies from the perspectives of questions, answers, users, platforms, fields and applications.
