Reddit is an online community of numerous subreddits, or conversation threads centered around a topic. Comments are upvoted or downvoted by other members of the subreddit, and the most popular and relevant posts about a topic are pushed toward the top of the thread. The communities are self-policed and moderated. Every subreddit has its own rules and culture.
Etiquette: Follow Reddit’s rules, which are published on their site, and each subreddits rules, if any. These are largely around self-promotion: Reddit’s many communities typically resent and even ban users that blatantly or secretly promote work they have done or that their professional organization has done.
Questions to ask yourself: Do I understand Reddit’s culture? Am I being transparent about where the content in my post is coming from and why it’s relevant to the subreddit? Am I being too self-promotional?
