The Hacker News Guidelines outline rules for submissions and comments to maintain quality discussion. Submissions should focus on topics that satisfy intellectual curiosity, avoiding politics, crime, and celebrity news unless novel. Users must submit original sources, avoid promotional content, and use clear titles without editorializing. Comments should be kind, thoughtful, and substantive, addressing arguments rather than attacking people. The guidelines emphasize good faith discussion, prohibit AI-generated content, and discourage flamebait or shallow dismissals to preserve the community's focus on curiosity-driven conversation.
