Founding and namingEdit
Quora was co-founded by former Facebook employees Adam D'Angelo and Charlie Cheever in June 2009. In an answer to the question "How did Adam D'Angelo and Charlie Cheever come up with the name Quora?" written on Quora in 2011, Charlie Cheever stated, "We spent a few hours brainstorming and writing down all the ideas that we could think of. After consulting with friends and eliminating ones we didn't love, we narrowed it down to 5 or 6 finalists, and eventually settled on Quora." Cheever went on to state, "The closest competition that [the name] Quora had was Quiver."
2010 – 2013: Early growthEdit
In March 2010, before the website even became available to the public, Quora, Inc. was already valued at $86 million. Quora first became available to the public on June 21, 2010. When the site first went online, it received widespread acclaim. The site at this point in its history was especially praised for its interface and for the quality of the answers written by its users, many of whom were recognized as experts in their respective fields. Quora's user base "exploded" almost instantly and, by late December 2010, the site was seeing spikes of visitors five to ten times its usual load—so much that the website initially had difficulties handling the increased traffic. When the website first came online and for many years afterward, Quora refused to show ads because, as the company stated in 2016, "...ads can often be negative for user experience. Nobody likes banner ads, ads from shady companies, or ads that are irrelevant to their needs."
In June 2011, Quora redesigned the navigation and usability of its website. Co-founder Adam D'Angelo compared the redesigned Quora to Wikipedia, and stated that the changes to the website were made on the basis of what had worked and what had not when the website had experienced unprecedented growth in December 2010. In September 2012, co-founder Charlie Cheever stepped down as co-operator of the company, taking an advisory role. Meanwhile, the other co-founder, Adam D'Angelo, continued to maintain a high degree of control over the company.
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.
2014 – 2017: Continued growth, first ads, and foreign-language versionsEdit
Over time, Quora evolved into what Theodore Schleier, writing for Vox, called, "a more organized Yahoo Answers, a classier Reddit, an opionated Wikipedia." The website became popular in elite tech circles. In April 2014, Quora raised $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 March 2016, Quora acquired the online community website Parlio.
In spite of this, this whole time, Quora was still not showing any ads and was still not making any revenues on its own. In April 2016, the company finally relented to pressures for it start making a profit and began a limited roll out of advertising on the site. The very first ad placement that the company accepted was from Uber. Over the next few years, the site began to gradually show more ads, but still maintained efforts to limit the number of ads and to keep the ads it did show relevant to the users seeing them.
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, beta versions in German and Italian were introduced. In September 2017 a beta version in Japanese was launched. In April 2018, Beta versions in Hindi, Portuguese, and Indonesian were launched. in September 2018, Quora announced that additional versions in Bengali, Marathi, Tamil, Finnish, Norwegian, Swedish, and Dutch were planned. In April 2017, Quora claimed to have 190 million monthly unique visitors, up from 100 million a year earlier. That same month, Quora was reported to have received Series D funding with a valuation of $1.8 billion.
2018 – present: Further growth and data breachEdit
In September 2018, Quora reported that it was receiving 300 million unique visitors every month. Despite its large number of registered users, Quora did not possess the same level of mainstream cultural dominance as sites like Twitter, which, at the time, had roughly 326 million registered users. This may have been because a large number of registered users on the site did not use it regularly and many did not even know they had accounts, since they had either created them unknowingly through other social media sites linked to Quora or created them years previously and forgotten about them.
In December 2018, Quora announced that approximately 100 million user accounts were affected by a data breach. The hacked information included users' names, email addresses, encrypted passwords, data from social networks like Facebook and Twitter if people had chosen to link them to their Quora accounts, questions they had asked, and answers they had written. Adam D'Angelo stated, "The overwhelming majority of the content accessed was already public on Quora, but the compromise of account and other private information is serious."
By May 2019, Quora was valued at $2 billion as a company and it was finalizing a $60 million investment round, which was led by Valor Equity Partners, a private equity firm with ties to Tesla, Inc. and SpaceX. In spite of this, the site still showed very few ads compared to other sites of its kind and the company was still struggling to turn a substantial profit, having only made $20 million in revenue in 2018. Several investors passed on the opportunity to invest in Quora, citing the company's "poor track record of actually making money." Schleifer characterized the disparity between Quora's valuation as a company and its actual profits as a result of "the high valuation for virtually everything these days in the tech sector."
Real name policyEdit
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. By default, Quora exposes its users' profiles, including their real names, to search engines. Users can disable this feature.
Quora has developed its own proprietary algorithm to rank answers, which works similarly to Google's 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.
- Requested Answers: 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.
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 is intended to help 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 is intended to keep 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.
Top Writers ProgramEdit
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. About 150 writers each year are chosen out of 200 million monthly unique visitors. 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.
Quora World MeetupEdit
Quora World Meetup started in 2017 as a tradition for Quora readers and writers to come know each other, network, and have fun. Quora World Meetups are organised by group of Quora contributors with a designated lead and as a contribution from Quora they usually send branded swag and stickers to the attendees. According to Quora, they defined the World Meetups as "This is our way of celebrating the global growth of Quora, and all of the readers and writers who have made it possible." The last meetup had nearly 3,000 writers from over cities and the 2018 World Meetups will come up from June 20–25. All other information about the Meetups can be found on The Quora Blog.
Quora was reviewed extensively by the media in 2010. 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.
Since 2014, Quora has attracted continued controversy for using robots.txt to ask crawlers such as the Internet Archive's Wayback Machine to not index or archive the site. Their stated reason is that the Wayback APIs do 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.
Quora was highly criticized for removing question details in August 2017. According to some users, the removal of question details limited the ability to submit personal questions and other questions requiring question details. According to an official product update announcement, the removal of question details was made to emphasize canonical questions.
