I'm also periodically surprised that topics that seem to be of core interest and very popular on HN just drop off the front page in a matter of hours. Meanwhile discussions like this one [0] (which stayed on the front page with not even 20 upvotes and 4-5 comments for almost 20h before some discussion picked up) seem to artificially stay on the front page for a day or more. It's probably less algorithmic and more arbitrary. [0] https://news.ycombinator.com/item?id=41067079 https://news.ycombinator.com/item?id=41067079
