Curious, why? Why mark the story that says it's from 10 hours ago, with lots of votes, as a dupe, and move comments to a newer story saying it's from 1 hour ago, with only a fraction of votes? Not criticizing, just curious.
The one we moved it to was submitted first, and we try to reward the first submitter of a story. We had to update the timestamp to give it full time on the front page but you should see that the ID is lower.
Ah thanks for replying, the updated timestamp had thrown me off. That makes perfect sense. Thanks for satisfying my curiosity!
Most likely just incompetence
