Reddit is a social news and entertainment website where registered users submit content in the form of either a link or a text ("self") post. Other users then vote the submission "up" or "down", which is used to rank the post and determine its position on the site's pages and front page. Content entries are organized by areas of interest called "subreddits".
Reddit was founded by Steve Huffman and Alexis Ohanian. It was acquired by Condé Nast Publications in October 2006. In September 2011, Reddit was split from Condé Nast, and now operates as a subsidiary of Condé Nast's parent company, Advance Publications. Reddit is based in San Francisco, California.
Overview
The site is a collection of entries submitted by its registered users, essentially a bulletin board system. Registered users, especially those who post new entries, or post comments to entries, are called "redditors.” Reddit itself is a portmanteau of "read/edit" and of "read it", i.e., "I read it on Reddit".
As submissions post to the site, redditors can vote for or against them (upvote/downvote). Each subreddit has a front page that shows newer submissions that have been rated highly. Redditors can also post comments about the submission, and respond back and forth in a conversation tree of comments; the comments themselves can also be upvoted and downvoted.
The home page of Reddit displays front page content from selected subreddits. There is a default set, but registered users can customize their set. Redditors can "friend" one another, which gives a redditor quick access to posting and comments of their friend list. Postings are typically a link to an external source, with a title provided by the redditor who posted it. Some redditors use the site as a personal bookmark collection. Others, relying on the size and activity of Reddit, and on the crowd sourced ratings of links, use it as a news aggregator.
Reddit also allows postings that do not link externally. These are called "self posts" or "text submissions". Reddit encourages links over text submissions, by allowing redditors to accumulate points ("karma") for highly rated links, but not for self-posts. Redditors also accumulate karma for highly rated comments, on posts of both kinds.
The commenting system and friend system, along with a certain "Reddit ethos" lend Reddit aspects of a social network, though not to the extent of Facebook, Google+, and other websites aimed at social networking.
Front page rank, for both the general front page and for individual subreddits, is determined by the age of the submission, positive ("upvoted") to negative ("downvoted") feedback ratio and the total vote count.[5] Dozens of submissions cycle through these front pages daily.
As of June 2013, commentary on the site is particularly active, with several communities generating thousands of comments per day.
The Reddit community has been known to socialize at local parks and bars around the world, and there are many localized subreddits for local meetings.
