Quora is an online knowledge market. Users ask and answer questions from other users, and read existing questions and answers. The site was founded in June 2009, launched in private beta in December 2009, and made available to the public on June 21, 2010.
Quora aggregates questions and answers to topics and allows users to collaborate on them by editing questions and suggesting edits to other users' answers. Quora's main competitors are social bookmarking sites like reddit, social networking sites like Yahoo Answers, LinkedIn, Answerbag and Answers.com, and expert question-answer communities like the Stack Exchange.
History
Quora was co-founded by two former Facebook employees, Adam D'Angelo and Charlie Cheever. D'Angelo quit his position at Facebook in January 2010 to create Quora and said he was inspired to create Quora because he thought: "that Q & A is one of those areas on the internet where there are a lot of sites, but no one had come along and built something that was really good yet." Quora's base of users grew quickly in December 2010.
In March, 2010 Quora received $11 million in funding from Benchmark Capital, valuing the start-up at $86 million.
Website
Quora is designed to be an online social form of a knowledge market. Users follow topics that they are interested in and questions and answers in those topics are displayed in the user's news feed. The service allows users to ask questions and give answers. Additionally, users can comment on the questions, and "upvote" or "downvote" answers. An "Answer Summary" can be created to reflect the consensus of the community; this summary is a wiki that can be edited by any registered user. Users can also create stand-alone "Posts", which resemble blog posts.
Technology
Quora uses Pylons and Comet for its backend and Ubuntu Linux as its operating system with MySQL as its database. It also uses Git and memcached. Quora uses Nginx as a reverse proxy server and HAProxy for load balancing. Quora has developed its own algorithm for ranking the answers, which works on similar principles to PageRank. Quora uses Amazon Elastic Compute Cloud technology to host the servers that run their website.
