This perspective on opinions doesn't seem accurate to me, e.g., opinion pieces (especially favorable) on Emacs, Neovim, and Blender seem to do really well here. I also disagree with the junk food characterization, I think people taking a strong stance on why they like something is often really valuable.
> There is another comment that opines that they want to see more daringfireball content on HN. I mean, they could just visit his site, or they could just hit https://news.ycombinator.com/from?site=daringfireball.net, but what they really seem to mean is that they want everyone else to see more content from DF.
For the record, I personally share things here when I think they're worth discussing, i.e., it isn't because I want people to see something, it's because I want them to talk about it.
