OK, perhaps I was a bit harsh. But there is already a very active place to discuss how SO should do things; it's called meta.stackoverflow.com. This discussion has been going on for years.
It's great to try to influence it, but as time goes on, the chances decrease that a newcomer has a point that hasn't been considered. That's just life. You don't see HN changing its format every week; newcomers adjust.
And if someone does have a good point, and it's not being considered, as we say, "fork it." The public Q&A data is available, or you could start from scratch.
HN frowns on the single sentence comment that does nothing but concur, so there ought to be an upvote which a parent can give that says, I agree, nice retort, I modify my concern and cheers, mate.
