Off topic: I posted this exact article four days ago: https://news.ycombinator.com/item?id=14813807

In the past, when I post exact duplicates, HN redirects me and automatically upvotes the original instead. I wonder why this doesn't always happen. (I'm not bothered, just curious.)

Double off topic: It's very interesting to see how much difference timing makes. My original had a single upvote, and this hit the front page.
