Module 6 — Commenting, conversation, and conflict

### How do you add a top-level comment vs. reply to another comment? Reddit's comment system is threaded, meaning replies can nest inside other replies to arbitrary depth. Understanding the difference between a top-level comment and a nested reply is fundamental to participating correctly in discussion. A top-level comment is a direct response to the original post itself, appearing at the root of the comment section rather than beneath any existing comment. On desktop, the composition box at the top of the comments section — labeled "Add a comment" or similar — is where top-level comments are written. On mobile, the "Comment" or "Add a comment" button at the bottom of the post creates a top-level comment. Top-level comments are the appropriate choice when you are responding to the original post's question or topic, adding a new perspective that does not directly build on something another commenter already said. A reply is a response to a specific comment within the thread. To post a reply, locate the comment you want to respond to and click or tap the "Reply" link beneath it. This opens a text box directly below that comment and will post your response indented one level deeper in the thread hierarchy, visually indicating its relationship to the parent comment. The reply will notify the commenter whose post you are responding to, via Reddit's notification system, which increases the chance they will engage with what you wrote. Choosing correctly between the two matters for conversation flow. If someone has already made a point you wanted to make, replying to their comment and agreeing or adding to it is more useful than writing another top-level comment with the same point — the latter fragments discussion. Conversely, if your observation is independent of any existing comment and speaks directly to the original post, a top-level comment ensures it gets evaluated on its own merits rather than being buried within someone else's thread. New users sometimes inadvertently post top-level comments when they meant to reply, producing confusing non-sequiturs that appear to address the post but actually reference a comment.
