Huh... I was sure this would have been posted before; I just posted it to get a quick link to the conversation.

Next time try the search box at the bottom of the page?

Probably not:

1. HN Search is kind of a hassle to use effectively, especially as compared to that handy bookmark.

2. This doesn't seem to have been posted before. (If it has, then see point 1!)

HN's deduplication is fragile and doesn't work for submissions more than a couple weeks old.

>>sp332+gd
OK, if this is a dupe then please provide the link it dupes. (I do genuinely want to see the previous commentary...) Or sockpuppet-downvote me again, whatever.

Assuming this wasn't posted anywhere other than Facebook, yours was its first submission to HN.

If HN detects a duplicate, it sends you to the previous submission. However, HN's duplicate detector is porous by design. We deliberately leave the door open for reposts, if a story hasn't had significant attention yet, and ask people not to exploit the loophole. This is so genuinely interesting articles can have multiple cracks at the bat.
