Quora is a question and answer website where users can ask and answer questions on any topic. Users can edit and improve content on most public spaces. While this allows for real answers from diverse communities, it also means information isn't always fact-checked before posting and profiles could be fake. For businesses, this open format allows free advertising but also leaves them exposed to any unfiltered questions or negative reviews from users. Overall usage and high-quality contributions from experts are growing over time.
