Ask HN: Is the Ask HN algorithm broken?

I'm guessing you're asking because of this submission (yours) from a little while ago that's somehow even off the Ask page, not just the front page, despite having a good amount of active discussion.
Ask HN seems to be more sensitive to two things than other discussions:
1. Comment:Score ratio. The ratio of comments to points is 3:1, 69 comments and 23 points as I write this. None of the discussion threads are very deep, but when a discussion has a lot of comments but not a lot of points it tends to get moderated (automatically, not by dang & co.) down faster. This probably relates to the flame war detection, though I've seen that kick in more often when comment threads get very deep and more linear than branching.
2. Flags. When Ask HN submissions get flagged, they move down faster than article submissions.
The Parekh discussion has a high score and a high comment count, so (1) is not applicable to it (more comments than points, but more like 4:3 so not over whatever the threshold may be). I have no idea if it was flagged, but if it was since it had active discussion the mods can turn off flags (as it impacts rankings) on a submission by submission basis.

Makes sense, I can see #1 being an issue
Mods have a way of boosting posts to refresh them back into the algorithm hence why you see some posts weeks ago showing back up
The points shown on a post are misleading. There are other, mostly invisible factors influencing the ranking of all posts, not just Ask HN. You can't even trust the timestamps on posts and comments, because mods occasionally decide to falsify them and make you think you're going crazy by inducing feelings of deja-vu.
How did this end up on the front page with 0 comments??
Enough upvotes in a short enough time. Now it'll be up there a bit longer because there's active discussion.
By making this comment you changed the outcome
mod mischief
For example I saw a post with time 6 hours ago with 7 upvotes ranks higher than a post with 22 upvotes 1 hour ago?
What is the logic of the ranking?
I've noticed this a lot recently, as in the last year or so
Also why is a post from 2 weeks ago still on the front page of ask?
