This seems like a good usecase for that "replies to multiple posts" feature i was telling you about in my other comment (would't it be nice if a mention of my other post was a click away? Unfortunately, the process for that is comparatively cumbersome in HN and i am not gonna post the link just to annoy you and make you realize the feature's importance)

4chan maybe a ton of bad things, but what it truly nails, is a simple-to-use and effective UI.

(Legend has it that whenever you speak of 4chan, moot makes an appearance. Wonder if it'll happen this time)

That is an interesting point.

It remains to be seen if two users are actually agreeing to the third person, or still continue to argue with their points
