This is a really awesome idea, but it's missing an option to give a comment with my confusion. It would be much clearer for the author if I could specify what exactly confuses me.
No, I think Swizec was saying that he wanted the ability to write text after clicking "Now you lost me!", to explain just why he is lost. For instance, he might click the button and then write "I don't know who you meant by 'they' in the second sentence." into a text field that popped up before clicking "Send Feedback". Giving more specific feedback might help Krista fix the exact part of the post that is broken more easily.
