There are many posts where users go away from the topic of the first post and quote those who responded recently, allegedly maintaining the meaning of the conversation.
Sometimes, it's usually a fundamental course that the topic and the body of the thread doesn't tally to be understood by the user. At times, OP of a thread do actually make it complicated so some forum members do jump across replies reading in between lines until they finds a reply which is understandable to them and then quote on it with their own terms.
