Reddit

Reddit is the internet's front page: a massive social news and forum platform where user-submitted content is ranked by a democratic upvote system.

Reddit operates as a proprietary social news aggregation and discussion forum, built on thousands of user-created communities called subreddits (r/science, r/gaming, etc.). Registered users submit content—links, text posts, images, and videos—which is then ranked by other members through upvotes and downvotes: the core mechanism. Posts with high engagement surface to the top of their subreddit and potentially to the main front page. This structure supports over 18,000 active communities and draws more than 80 million weekly active unique users, establishing it as a primary source for real-time conversation and niche interest groups globally (as of late-2025 data).
