Y'all,<p>As of this writing...<p>A WSJ Bitcoin post from today has 373 points, 207 comments, was posted 10 hours ago, and is on the homepage.<p>This other post "Reconsider" from today has 558 points, 117 comments, was posted 5 hours ago, and is __not__ on the homepage (anymore).<p>Source: http://imgur.com/a/vNGLm<p>Question for all: what determines lifespan of a post on HN homepage?
There's a few things.<p>1) Upvotes keep a post on the front page longer.<p>2) Flags move a post off the front page quicker.<p>3) "Flame detection" moves a post off the front page quicker<p>There's probably other stuff there too, such as dupe-detection, vote ring detection, etc.
There's an analysis at <a href="http://www.righto.com/2013/11/how-hacker-news-ranking-really-works.html" rel="nofollow">http://www.righto.com/2013/11/how-hacker-news-ranking-really...</a>, also I know 'pg posted the Arc code that powers the ranking in a HN post several years ago.
