First, I'm extremely appreciative of Hacker News, its moderators, and the forum it provides for poor builders like myself to get some eyeballs on our infant products at no cost via Show HN.
However, it seems the 40-comment penalty is being applied to Show HN posts, which seems counter-productive to me. Isn't the whole point of Show HN to generate healthy discussion and answer user questions? Shouldn't they be exempt?
(Yesterday I posted a Show HN that had reached #15 on the front page when the 40th comment came in. Ding! Welcome to page 3. Irony: Several comments were my own, replying to questions.)
Just read the part of the linked article relevant to the 40 comment penalty. My question is: assuming that this algorithm works in general, why would it need to be different for Show HN? What makes them different with respect to vote to comment ratios?
According to that article, the 40 comment penalty is applied to all posts. Putting "Show HN" in your post probably didn't change that.
The algorithm for the front page favours newer things and attempts to generate traction for discussions. I'm speculating here but once something hits 40 comments, not only can it be deemed 'controversial' it could also just mean the article may be able to sustain itself better without more eyeballs, and the front page can 'move on' to other newer things.
Ultimately the Hackernews algorithm should prevent anyone using it as a cheap referral source. 40 comments should have given you some valuable feedback, which is what Hackernews is good for, primarily.
Personally I think "generate healthy discussion" should be the goal of all HN threads, which is why I think comment-count penalties are unproductive. How do you tell the difference between "vigorous debate" and a "flame war"? If the algorithm utilized NLP to analyze the tenor of the discussion, that would be one thing, but upvotes vs. comment count is a troubling metric. I want to read threads where people are passionately discussing a topic with long back-and-forth debates. If that's a "flame war" then I'd like more flame wars, please.
From the guidelines, "Please don't post on HN to ask or tell us something (e.g. to ask us questions about Y Combinator, or to ask or complain about moderation). If you want to say something to us, please send it to hn@ycombinator.com."
I've been lurking here for quite a while before I started posting and I strongly suspect it's the ratio of upvotes to comments that trigger this. There may be a "recalculation" at 40 comments for performance or other reasons, but I've seen plenty of other stories with hundreds of comments and an equal or greater number of upvotes - on occasion passing 1000 - that stay on the front page for the better part of a day.
