Does HN need a dupe link detector? A better one?
ars: HN doesn't need a dup detector - it has that, humans.It needs a better policy/idea of what to do about dups.My suggestion:Merge the comments, have a mod pick a title and url for the main view. Show the other/alternate titles and urls on the comments view.The mod ranking is whichever is higher, and any future mods get credited to all submitters.Have a flag called dup, which asks you for the id (or url) of the dup, and notifies a mod.
