Quora

Quora was created in 2009 and made available to the public in 2010. Adam D'Angelo, one of the founders, previously worked for Facebook before leaving to launch Quora, a question-and-answer site. Quora is a crowdsourced question-and-answer website that allows users to pose questions and get answers - sometimes known as an answer site.

Quora is named after the term "Quorum", which means “to come to a consensus” or “come to an agreement”. Because Quora is a question-and-answer site, you will find a lot of helpful information there. Users visit Quora primarily for two reasons: to obtain knowledge and to provide information. When you provide information and answer questions on Quora, you cite your skills and expertise as proof that you are knowledgeable about the subject. When you go to acquire information, you type your question, and the site recommends people who, based on their qualifications, would be able to respond to your questions. After a user creates a Quora account, they are free to ask or answer any question they want. Questions need to be short and precise and the relevant topic tags need to be verified before the question is posted. You may network one-on-one as well as participate in a content-based community.
