Depends on how "smart" HN's systems are. They're different URLs: https://www.cbc.ca/radio/quirks/scientists-develop-transparent-wood-that-is-stronger-and-lighter-than-glass-1.5902739 https://www.cbc.ca/radio/quirks/scientists-develop-transpare... https://www.cbc.ca/1.5902739 https://www.cbc.ca/1.5902739 Except the latter link redirects to the former. I'm guessing HN only compares the URL.
