I think the larger problem is that comments that aren't emotive, but are reasonably insightful get ignored. HN quickly trains newcomers not to bother with them, and to go for pithy zingers.

Indeed, this is pretty easy to notice. When I look at my posts, and see which ones are upvoted, it's mostly the ones that are short and emotive.
The ones in which I really put some effort into explaining something, looking up some information, or explaining my point, usually get only one or two upvotes, if any at all.
