Ask HN: Is HN's duplicate url detection broken?
I noticed that recently some stories are submitted more than once, and the duplicates make it to the front pages. I thought HN detects this and redirects similar submissions to the first one.
Examples:
Show HN: Whetuu – a zero-config cross-shell prompt written in Zig (https://github.com/yamafaktory/whetuu)

So if an initial submission gets overlooked, after a number of hours someone submitting it again is ok. (sometimes neither will go anywhere) Stuff moves fast around here tho. It's more about keeping the posts fresh and not repeating our discussions over and over.
