HN feature request: "I read the article" checkbox
Even better would be an account setting to allow you to hide comments with the checkbox unchecked.
It would save me time and frustration to simply ignore and avoid responding to comments by people who never read the submitted article. I don't wish to interact with such people.
I realize, of course, that commenters could mislead by checking the checkbox even when they haven't read the article. However, over the years I've seen a lot of commenters who are quite open and honest about the fact that they're here only for the comments, not the articles. Indeed, this feature request was inspired by my recent interaction with such a person, who admitted (after the fact) to not reading the article.
