These are fine preferences to have, and I don’t disagree one bit. I agree that in this particular case, a thread on the first post would also be appropriate. People have different reasons for posting than you do, and many/most are valid/compatible with HN guidelines. Your goals of centralizing discussion I tend to agree with, but I’m making a broader comment than this specific submission. There are perfectly valid reasons to prefer to make a point on a submission with fewer comments than one with many comments, especially if one hopes to not have their signal lost in the noise. No one is forcing you to post these dupe notifications, and I actually really appreciate that you do. I just mostly take ire with calling them dupes when they’re not an exact URL match or redirect, because the word dupe in the context of discussion boards has a highly specific meaning to me that predates my usage of HN, and also the existence of HN, and even web forums. Not that it matters in the context of HN, I just find it slightly grating and would prefer that other instances be called “related” posts or something, but I don’t necessarily think you should change your behavior. I don’t know why I am like this, and I can see how it is a silly thing to care about, and minor quibbling point besides. But hopefully that helps you understand why I find my good faith posts being dismissed or labeled as dupes when they’re not dupes frustrating. I also understand your usage of them being duplicate discussions, I just don’t think that’s really a problem on HN at all compared to actual duplicate exact URL match submissions. Please do keep posting your dupe link notices though, whatever you call them lol
