Just curious: Is someone gaming the point system a bit here? I just got two rapid-fire down votes for recommending a very relevant section from Feynman's QED book, on a question about whether complex math is required for quantum physics. Even if you don't agree with Feynman's perspective, you'd certainly think that a Nobel prize winner's very clear opinion on the topic might be relevant! And no explanatory comments, hmm! Fascinating dynamics, that.
If this is some case of aggressive gaming, is there a mechanism to moderate it? I don't know how often this problem arises, but it's an interesting one. If relevant references get fast-zinged on a regular basis, that can't be good for the overall answer quality of the group.
