Yes? It is not currently even on page 3 or 4 even if it got almost 2000 points. This is probably due to moderated behavior or else it would still be on the frontpage since it's such a big story.

The old HN ranking algorithm is roughly:

    (votes - 1) / ((item_hour_age+2)^1.8)

The current ranking might have some tweaks, but there is exponential decay.

It meas that using the old algorithm, the article with 1667 points and 1 day old (24-48 hours) has score between 4.5 and 1.5. Currently the last item in the front page has 242 points, 11 hours ago, so it would have 2.5 points.

I think you are correct in this case. I found the link on page 4, I just searched badly before but in my defense HN can be pretty hard to read sometimes.

All of these threads rapidly go into dumpster fire territory, so I imagine they get bounced out pretty quickly by the automated flamewar detectors, if not the various classes of flags.

I'm not saying it is not the correct thing to do, just that it seems like it's happening. But just stating this makes people downvote which is very confusing to me.
