There was a story posted to Hacker News, The Return of the Super-Elite from Jacobin magazine. It was on the front page for a little bit of time. I refreshed and it was on the 2nd page.
5 hours later and it's down to #113, page 4. It has 88 points. The second youngest submission on page 4 is 16 hours old. On page 3, the youngest item is 6 hours old, and has only 7 points. So this article is newer, has a respectable amount of points but within 5 hours has been relegated to page 4, whereas an item that has fewer points and is 1 hour older is sitting on page 3.
edit: the rank keeps dropping, when I first wrote this post it was at #111, then #112, and when I submitted it was at #113, I just refreshed and it's at #114. Other submissions near the range of points and hours are ranking on page 1. On page 5 all items are from 1, 2 or 3 days ago.
I've noticed that any pro-unionization talk seems to disappear much more quickly than other stories.
So let's get our tinfoil hats on and ask is Hacker News suppressing leftist articles or suppressing articles of a certain type altogether?
Or maybe it's just a conspiracy of a bad algorithm for determining where submissions rank?
