Reddit is an online platform that enables users to submit links, create content, and have discussions about the topics of their interest. Users can post links to content on the web and then the other users can vote the posted links up or down, causing them to appear more or less prominently on the site’s home page. The site has discussion areaswhere users can discuss the posted links, and vote for or against others’ comments. When there are enough votes against a given comment, it will not be displayed by default, although a reader can display it through a link or preference. Users who submit articles that other users like and subsequently “vote up” receive “karma”, points which a user receives as a reward for submitting interesting articles.
