Quora is a question-and-answer site where questions are asked, answered, edited and organised 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 additional users' answers.
Quora was co-founded by two former Facebook employees, Adam D'Angelo and Charlie Cheever. D'Angelo resigned from his position at Facebook in January 2010 to create Quora. He said that he and Cheever were inspired to create Quora because "we 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.
Quora had an estimated 500,000 registered users, as of January 2011. In June 2011, Quora redesigned its website, in order to make information discovery and navigation easier. Some noted that the redesigned site had definite similarities to Wikipedia. Quora released an official iPhone app on September 29, 2011, followed by an Android app on September 5, 2012.
In September 2012, Quora announced that co-founder Charlie Cheever was stepping back from a day-to-day role at the firm, although he would continue in an advisory role.
In January 2013, Quora launched a blogging platform.
Quora launched 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 additionally announced in May 2013 that all its metrics had tripled relative to the same time in the prior year. In November 2013, Quora introduced a feature called Stats to allow ll Quora users to see summary and detailed statistics regarding how a large number of people had viewed, upvoted, followed, 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 additionally one of the members of the Summer 2014 Y Combinator batch.
In March 2016, Quora acquired Parlio. In April of that year, the company additionally began a limited rollout of advertising on the site.
In October 2016, Quora launched Quora en español to the public.
In March 2010, Quora received funding of $11 million from Benchmark Capital, valuing the start-up at $86 million.
In May 2012, Quora raised $50 million in Series B funds, valuing the firm at over $400 million, bringing their total funding to $61 million. Co-founder D'Angelo, who owns 0.8% of Facebook stock, additionally invested $20 million of his own money in the B round.
In April 2014, Quora announced an $80 million Series C round of funding, valuing the firm at over $900 million. The funding was led by Tiger Global Management.
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 criticised Quora for being a "horrid service for blogging", and although a decent question and answer website, not substantially better than competitors.
In 2010, D'Angelo and Cheever were among five named "Smartest Engineer runner-up" in the "smartest people in the tech" article by CNNMoney. They were additionally both listed in Inc. magazine's "Top 30 Under-30" entrepreneurs list of 2011.
In August 2012, blogger Ivan Kirigin pointed out that it was possible for acquaintances and followers to see his activity including which questions he'd 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.
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 don't give users a way to censor answers that they might 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 recognise individuals who's made especially valuable content contributions to the site, and encourage them to continue. 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're particularly invested in the site, the programme creates a feedback loop of user engagement.
