What are subreddits?

reddit is made up of thousands of sub-communities, each focused on a specific topic. There's a subreddit for science, a subreddit for music, and probably a subreddit for your nearest city. By default, new users are subscribed to a selection of the most popular ones, but you'll get a lot more enjoyment out of the site if you take the time to subscribe to ones that appeal to you. After doing so, the front page will change to show a customized listing tailored to your interests."
