Reddit.com vs Quora.com

Reddit is a social news accumulation, web content rating, and conversation site. Registered members submit content to the site for example, text posts, and pictures, which are then voted up or down by other members. Posts are organized by subject into user-created boards called "communities" or "subreddits", which cover an assortment of topics, for example, news, politics, science, movies, video games, music, books, sports, fitness, cooking, pets, and picture sharing. Submissions with more up-votes appear towards the highest point of their subreddit and, if they they get enough up-votes, eventually on the site's front page. Despite severe guidelines restricting harassment, Reddit's administrators spend impressive assets on moderating the site. 

As of February 2021, Reddit ranks as the 18th-most-visited site on the planet and 7th most-visited site in the US, according to Alexa Internet. Around 42-49.3% of its user base comes from the United States, followed by the United Kingdom at 7.9-8.2% and Canada at 5.2-7.8%. 

Reddit was established by University of Virginia flat mates Steve Huffman and Alexis Ohanian, and Aaron Swartz in 2005. Condé Nast Publications obtained the site in October 2006. In 2011, Reddit became  an independent subsidiary of Condé Nast's parent company, Advance Publications. In October 2014, Reddit raised $50 million in a funding round led by Sam Altman and including investors Marc Andreessen, Peter Thiel, Ron Conway, Snoop Dogg, and Jared Leto. Their investment valued the company at $500 million then. In July 2017, Reddit raised $200 million for a $1.8 billion valuation, with Advance Publications remaining the majority stakeholder. In February 2019, a $300 million funding round led by Tencent brought the company's valuation to $3 billion. 

On June 5, 2020, Alexis Ohanian resigned as a member from the board because of the George Floyd protests and requested to be replaced "by a Black candidate". 

On December 13, 2020, Reddit declared it had gained short-form video social platform Dubsmash, employing its whole team, with the expectation coordinating its video creation devices into Reddit.
