I think it&#x27;s always more honest to either append, or modify and summarize the changes if shortly after comment creation. If it&#x27;s immediately after and it&#x27;s just typo&#x2F;grammar fixes sometimes I&#x27;ll just modify without a note.<p>My thinking is that you can&#x27;t have an honest discussion if people can&#x27;t count on their replies applying to the parent after the fact, and if I&#x27;ve screwed up enough that I want something off the record, I <i>really</i> should have thought more before writing it, so leaving it and the sting of it&#x27;s continual viewing is a good reminder for the future.
