It's super tricky because how do you decide what constitutes a 'topic'? For example, are all the various ChatGPT threads related? What about coverage of an event (e.g. there are six or seven threads regarding the recent earthquake in Turkiye—all empty apart from https://news.ycombinator.com/item?id=34672314 https://news.ycombinator.com/item?id=34672314 —however I've seen it where basically the same story is being carried across several outlets and discussions are on the same topics, just one post gets more traction than the other). It's easy enough to link articles which refer to the same exact source and mark duplicates, but harder to link posts which rely on different sources to cover the exact same topic.
