Gotta question? Or maybe an answer? It seems more and more social media sites are listening. LinkedIn has long had a LinkedIn Answers feature, where people can ask business-related questions and get answers from experts in the community. Facebook added Facebook Questions late last year, and Quora, a relatively new kid on the block, is based entirely on questions and answers from members of its growing community.

Question and answer features provide an excellent opportunity for finding information and for setting yourself apart as an expert in your field. On Quora, for example, members can view questions based on topic, follow specific topics that interest them to see what others are asking, follow specific questions to see new answers as they appear, and rate answers, so the best answers work their way to the top of the heap. The Quora website is built on a structure similar to Wikipedia and uses moderators to ensure content is appropriate.

Starting out on any new social site can be a bit daunting. Before asking a new question on Quora, Facebook Questions, or a similar website, look for similar questions that have already been posted. With thousands of questions in place on virtually every topic under the sun, don’t be surprised if your question has already been asked and answered. As you become more familiar with the site, start answering questions that fit your area of expertise. Engage with other users who share your interests, and stay involved.
