HN already does this to some degree, the "reply" button is hidden as you get deeper into a tree of comments.
You can, of course, click on the timestamp and see it anyway, so it's more of a speedbump for folks who don't know all of the details of how the forum works than a true delay, though.
If you take it to the extreme, a youtube video being posted and everyone having to wait 5 minutes to comment, there is enough people that will see it at 4.30 to have a visceral reaction and post inflammatory comments. You can extend that down to each level of comments.
