Reddit is an entertainment, social news networking service, and news website where registered community members can submit content, such as text posts or direct links, making it essentially an online bulletin board system.
Registered users can then vote submissions up or down to organize the posts and determine their position on the site’s pages.
The submissions with the most positive votes appear on the main page or the top of a category. Content entries are organized by areas of interest called “subreddits”.
The subreddit topics include news, gaming, movies, music, books, fitness, food, and photosharing, among many others.
