I appreciate it when people post a link to duplicated stories Can't help but think though; Every comments entry in the HN database could benefit two extra nodes The last comment would always point to (a list of) nodes subsequently confirmed as dupes (future material). The first comment would always point to previously confirmed as dupes ("previously discussed"). That could be fun to navigate. (modulo debate on what is a dupe or update, of course)
