Quora is a question-and-answer site where questions are asked, answered, edited, and organized by its community of users. Its publisher, Quora Inc., is based in Mountain View, California. The company was founded in June 2009, and the website was made available to the public on June 21, 2010. Users can collaborate by editing questions and suggesting edits to answers that have been submitted by other users.
Quora was co-founded by former Facebook employees Adam D'Angelo and Charlie Cheever in June 2009. About choosing the brand name, Cheever stated that 'I associate it with "quorum" or public congregation. We spent a few hours brainstorming and writing down all the ideas that we could think of. The closest competition that Quora had was "Quiver" but we eventually settled on Quora'. 
In September 2012 Quora announced that co-founder Charlie Cheever would leave his position as a co-operator of the company, though he would continue in an advisory role.
In January 2013 Quora launched a blogging platform allowing users to post non-answer content on their profiles.
Quora launched a full-text search of questions and answers on its website on March 20, 2013 and extended the feature to mobile devices in late May 2013. It also announced in May 2013 that all its usage metrics had tripled relative to the same time in the prior year. In November 2013 Quora introduced a feature called Stats to allow all Quora users to see summary and detailed statistics regarding how many people had viewed, upvoted, and shared their questions and answers.TechCrunch reported that, although Quora had no immediate plans for monetization, they believed that search ads would likely be their eventual source of revenue.
In April 2014 it was announced that Quora was raising $80 million from Tiger Global at a reported $900 million valuation. Quora was also one of the members of the Summer 2014 Y Combinator batch.
In October 2016 Quora launched a Spanish version of its website to the public. Following this announcement, in early 2017, a beta version of Quora in French was announced. In May 2017 the launch of beta versions in German and Italian launched. In September 2017 a beta version in Japanese was launched.
In April 2017 Quora was reported to have received Series D funding with a valuation of $1.8 billion.
Quora has developed its own proprietary algorithm to rank answers, which works similarly to Google PageRank. Quora uses Amazon Elastic Compute Cloud technology to host the servers that run its website.
Currently, Quora has different ways to recommend questions to users:
- Home feed questions recommendations: In this method, each user will have a timeline that is personalized to their preferences. Quora also provides "interesting" questions that are relevant to the user's preferences. This will lead to the user either answering that question or refers another user to better answer it.
- Daily Digest: In this method, Quora sends a daily email containing a set of questions with one answer that is deemed the best answer given certain ranking requirements.
- Related Questions: In this method, whether the user is logged in or not, a set of questions that relates to the current questions will be recommended and displayed on the side. This will help the user navigate through the questions and find what is more relevant to their preference.
- Ask to Answer: This feature enables the user to request another user's answer to a question that they feel is fit or better suited to answer that question.
According to Robert Scoble, Quora succeeded in combining attributes of Twitter and Facebook. Later, in 2011, Scoble criticized Quora for being a "horrid service for blogging" and, although a decent question and answer website, not substantially better than competitors.
Quora supports various features to moderate content posted by users. The majority of content moderation is done by the users, though staff can also intervene.
- Upvote/Downvote – Users can rank answers based on how relevant or helpful they found the answers to be. This feature helps maintain the quality of content posted online. The more upvotes an answer receives, the higher it is ranked, and it shows up on top of the searches related to the question. If an answer is ranked poorly, it is “collapsed” and will not show up in people’s feeds.
- Report Answer – Users can report plagiarism, harassment, spam, factually incorrect articles, etc. This keeps sub-standard content under check.
- Suggest Edits – Users make suggestions to improve an article by proposing changes to it. The proposed changes are also made visible to the original author of the question or answer and can be either approved and published or rejected.
Quora allows users to create user profiles with visible real names, photos, site use statistics, etc., which users can set to private. In August 2012 blogger Ivan Kirigin pointed out that acquaintances and followers could see his activity, including which questions he had looked at. In response, Quora stopped showing question views in feeds later that month.citation needed By default, Quora exposes its users' profiles, including their real names, to search engines. Users can disable this feature.
In 2014 a controversy arose about Quora's policy to restrict the Internet Archive's Wayback Machine from crawling their site. Citing possible user remorse over previously posted content, the Wayback Machine was banned entirely from crawling Quora.
Quora has attracted controversy for using robots.txt to forbid the Internet Archive's Wayback Machine from crawling the site. Their stated reason is that the Wayback APIs as of 2016 does not give users a way to censor answers that they may regret previously posting. Critics have raised concerns about the fate of Quora's data if the site ever goes offline and recommended Stack Overflow as an easily archived alternative.
Top Writers Program
In November 2012 Quora introduced the Top Writers Program as a way to recognize individuals who had made especially valuable content contributions to the site and encourage them to continue. This has inspired both young and experienced writers. Top writers are invited to occasional events and receive gifts such as branded clothing items and books. The company believes that by cultivating a group of core users who are particularly invested in the site, the program creates a feedback loop of user engagement.
