I work in healthcare (or health-tech), I sometimes forward articles from HN to colleagues or higher management. Often times I regretted that based on comments that came in later on articles. So now I muster up the discipline to wait some hours, keep the tab with comments open en refresh every now and then. I hardly ever get disappointed and the comments reveal the true value of an article almost without fail and always with extra resources to back up why a claim is true, false or questionable. I love this community for this reason and it provides a lot of value to me and via me my colleagues.

A good example is the recent discussion on the amyloid plaque "cabal" [0]. The comments confirm, but also attenuate the article, and together with my own experiences in science I feel confident to forward the article. Comments and discussions such as [1] are clearly from people deeply involved in the field or at least from very knowledgeable people, and they nicely balance the often polarizing articles.

Imho the HN algorithms seem to work very well in getting quality content to the top, given time (an article may well be gone from the home page by then).
