OP here..

Yes, I agree that HN is the place to discover the most interesting, coolest and weirdest stuff on the internet but unfortunately, sometimes, these posts don't get enough traction in their first minutes and once they got pushed to the second page of newest submissions, they are technically dead!

Fortunately, HN had introduced what's called pool, or second chance, where the mods of the site periodically watch for past submissions and pick what they believe is interesting then throw it to the front page and see if it sticks by having users upvoting it.

Leatherman story was one of those cases. I submitted it three days ago without getting a single upvote and was surprised to see it made it to the front page this morning.

I remember getting a second chance with my submission for non-explosive demolition agents.

The mods didn't put it on the front page themselves but instead emailed me with an invitation to repost.
