Reddit, stylized as 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. Reddit is based in San Francisco, California. Content entries are organised by areas of interest called "subreddits". "IAmA" is a subreddit. In an IAmA post, a person will post what they are, and other people will ask the original poster about himself/herself.
