What's reddit, you ask?  Wikipedia says: "reddit (pronounced /ˈrɛdɪt/)^[3] is a social news website where the 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."
