On Reddit, registered members submit content to the site such as links, text posts, and images, which are then voted up or down by other members. Posts are organized by subject into user-created boards called “subreddits”, which cover a variety of topics including news, science, movies, video games, music, books, fitness, food, and image-sharing. Across 2018, Reddit saw 153 million submissions, 1.2 billion comments, and 27 billion upvotes from its users.
