Reddit is a content aggregation site. What this means is people from all around the world go onto Reddit to share content they’ve either made or found with other Reddit users. Once the content is uploaded, the entire Reddit user base can either “upvote” or “downvote” the content based on how relevant, useful, or just interesting they think it is. The more something is upvoted, the higher it rises on the list of content populating the site and the more people see it, while downvoting does just the opposite! And that’s the entire basis of Reddit!
