Fair. I wish low quality submissions received similar treatment to low quality comments, or at least had their own category, separate from the main page.

There will always be a range of views about whether an article is good or not; there's no universal definition of “low quality submission”. HN’s ethos is to surface content that “gratifies intellectual curiosity”. Often we only really know whether an article fits that description once we see the discussion thread. You're welcome to flag submissions you think are not fit for HN, or to email hn@ycombinator.com to point out why an article is unfit for the front page. And you can make a substantive comment critiquing the article.
