I am not sure this will make the recommendation better. For me, there are three components to recommendations: relevance, novelty and quality. From my experience, medium gets the relevance right, the problem is the other two. I keep getting clickbaits (low quality) and slight variations of articles I read dozens of times before (lack of novelty). The show me less like this seems to target the relevance problem though which isn’t really the biggest problem, at least for me
