It is a social news website where users can post links their
content on the web and have other users vote the posted links up or down,
so that the links are either prominently displayed on the reddit home page or not at all.
Indeed each subreddit has a front page that shows newer submissions
that have been rated highly.
The site has
discussion areas where users may 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 which other users like and
subsequently "vote up" receive "karma", points which a user
receives as a reward for submitting interesting articles.
Reddit also includes
several topical sections called subreddits, which focus on specific topics,
including programming, science, and politics.
