Out of curiosity, anyone knows why would this post be removed from the front page?

I was excited see that the post is getting engagement. I saw it in 3 position. Then checked an hour later and it is nowhere to be seen.

I am assuming this is some sort of opportunistic algorithm at play that gives a chance to a post, but removes it if it is not performing, but curious if anyone has more details.

HN submissions tend to be in the front page when they receive a bit of early votes within (roughly) the first hour, but they disappear rather quickly without further votes. Given that this submission was only 3 hours old when you posted this comment, it is quite expectable. (For the record it's now in the fifth place, suggesting that it has eventually received enough votes to stay in the front page later.)

Makes sense. I am just curious about the logic behind the algorithm, more than anything else.
