What Is Reddit and How Does It Work: A Complete Guide
Reddit is one of the most singular and powerful platforms on the internet, a loose constellation of forums and chat rooms that drives the memes and news at the bleeding edge of web culture, even when much of the world isn’t paying attention.Often described as the “front page of the internet,” Reddit is not a typical social networking site but a network of thousands of communities with their own unique norms, customs and users ‘subreddits’
The majority of which feel more like a forum than what people generally think of as social media. By 2025, Reddit has hundreds of millions of active accounts, at one time ranked as one of the world’s top 10 websites.
What Is Reddit?
At its core, Reddit is a site where people gather to talk and share news. It's not like places such as Facebook or Instagram that are all about profiles or friends. Reddit is built on topics and things people like. Here, users, who are known as redditors, can post content like links, texts, images, and videos. Other users have the power to vote these up or down. This voting decides which posts get seen by more people on the front page and which ones get lost.
The name “Reddit” is a play on words with the phrase “read it”“I read it on Reddit.” Founded in 2005 by Steve Huffman, Alexis Ohanian and Aaron Swartz, the platform has grown into a cultural behemoth, shaping politics, finance, memes, gaming and much else besides.

The Structure of Reddit: Subreddits
Reddit is built on subreddits/individual communities around a certain topic, hobby, or interest. Subreddits are denoted by prefixes such as r/news, r/gaming, or r/explainlikeimfive (the latter of which features user-explanation of complicated subject material) Set up for just about any interest (besides tubgirl fetishism, we suspect), the sub is actually aimed at the equally mainstream and freakily specific (e.g. r/birdswitharms or r/BreadStapledToTrees) As of 2025, there are over 138,000 active subreddits, each with their own moderators, rules and culture.
How Subreddits Work
Making: Any user can make a subreddit if the theme isn't out there yet and it fits the site’s rules on content.
Running: Volunteers run subreddits. They check if people stick to the rules and keep content right for the community. Some subreddits ask for an older account or some karma (points) to stop spam and bad acts.
Rule 1: Posts must link to WoW. Only those fit in here.
Rule 2: No personal info at all! If posts break these laws, they can be taken off, and users who keep it up can get a short or long ban.
Finding: You can look for subreddits with the search tool, by looking through r/all or r/popular, or by asking in r/findareddit for tips.
The Reddit Experience: Posts, Comments, and Voting
Posts
Posts are the lifeblood of Reddit. Users can submit:
Link posts: Direct users to external websites, articles, or media.
Text posts: Initiate discussions, ask questions, or share stories.
Image and video posts: Share visual content directly on Reddit.
Posts are displayed in a feed, with the most popular (upvoted) content rising to the top.
Comments
Every post kicks off a comment thread in which readers hijack the post topic to discuss content, pose questions, and often argue amongst themselves. Ratings of comments are also allowed, with the most popular comments rising to the top of the thread
Voting System
Reddit’s voting system is central to its operation:
Upvote: Indicates approval or appreciation of a post or comment.
Downvote: Indicates disapproval or that the content doesn’t contribute to the conversation.
Net score (upvotes minus downvotes) determines the post position. Highly upvoted posts get featured on subreddit front pages, and even in some cases on Reddit’s global front page. But the voting system is not a popularity contest; it is meant to surface high-quality content and filter out low-effort or off-topic content.
Karma
Karma is a user’s reputation score, earned through upvotes on posts and comments. There are two types:
Post Karma: Earned from upvotes on posts.
Comment Karma: Earned from upvotes on comments.
Karma doesn’t unlock features, but high karma signals an engaged, respected community member. Conversely, a pattern of downvoted content can lead to posting restrictions in some subreddits.
The Front Page and Personalization
If you head to Reddit without signing in, you see a front page filled with the most popular posts from all of Reddit (except for NSFW and a few filtered communities). This would be r/all or r/popular
After signing up and subscribing to subreddits, your home feed gets customized, displaying top posts from communities you follow. You can continue to customize your experience with the search, suggestions, and curated lists inside Reddit

Reddit Jargon and Culture
Reddit has its own language and etiquette:
OP: The first one to post in the thread.
TL;DR: "Too long; didn't read," a short form for long posts.
TIL: "Today I Learned," shared to tell cool facts.
Reddiquette: Unwritten rules to be nice and helpful.
AMA: "Ask Me Anything," a chat with a special guest.
IAmA: "I Am A," how AMA chats start.
NSFW: "Not Safe For Work," for grown-up or touchy stuff.
Mod: Short for moderator, runs a subreddit.
Admin: Reddit worker in charge of all the sites.
Understanding these terms helps newcomers navigate conversations and avoid faux pas.
