Maybe when the same URL is posted again in HN, the platform should automatically insert a first post with links to the previous discussions, as someone did here. It’s not irrelevant to repost, but it could be useful to have pointers to previous conversations. Similarly, the platform could warn the poster that its a repost (a bit like stackoverflow does, but simpler - just using link equality).
