When asking ChatGPT to write comments, consider using the SmartGPT approach and break up the task into two prompts. The first prompt should generate options to be evaluated by the second prompt.
Prompt #1 "Let's write a comment for Hacker News. The title of the article is {XXX}. You didn't click on the link, so you don't know what the article is actually about. The current top comment is {YYY} by user {bar} with karma {83939}. I want you to write a comment in response to {ZZZ} by user {foo} with karma {9001}. Keep your comment in a single long paragraph and use jargon. Write two comments one supporting user {foo} and one as a rebuttal."
Prompt #2 "You are a resolver tasked with picking which of two comments will earn the most karma on Hacker News. The first comment is in support of the comment {ZZZ} by user {foo} with karma {9001}. The second comment is a rebuttal. Pick one and explain step-by-step why you believe the comment would receive more karma than the alternative."
