I'm curious how the algorithm works, as it doesn't seem to work as I'd expected.
My first thought was to go back and look at the day I launched my startup with at Show HN [1], which got over 700 points and was at #1 from roughly noon to 2 AM the next day (PT). Sure enough, this post shows up in the #2 slot on the day I posted it (Sept 5, 2013) [2], but it doesn't show up at all on the following day [3].
This is strange because it was at #1 at the beginning of this day (assuming that's midnight PT) and was on the front page for much of that day. Even when you go hundreds of entries down into the Sept 6 page, it doesn't show up.
Any idea how the algorithm works that it's generating these results?
