Reddit is a platform for online communities to submit links, create content, and have discussions about whatever topic that interests them. Users can post links to content on the web and 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 posts on the site are classified under topics such as random, gadgets, sports, gaming, pics, videos, music, funny, movies, books, history, food, philosophy, television, jokes, art, and more. These topic sections are called subreddits, which can be created and moderated by users. There are currently over 130,000 active subreddit communities. The Reddit home page is akin to a social media newsfeed, with each user's subreddit subscriptions generating the posts that are displayed.
Reddit was launched in 2005 and is headquartered in San Francisco, California.
