It is a neat toy, and I'm glad you posted the link to it.

The reason I got so mad is that Warren Huelsnitz's attempt to draw inferences from these - even weak, probabilistic, Bayesian inferences - were appallingly ignorant for someone who claims to be a high-energy physicist. What he was doing would be like my dad, in the story from his blog post, trying to prove that gravity was created by electromagnetic forces because Roger Blandford alluded to an electromagnetic case in a conversation about gravity waves. My dad knew that wasn't a true lesson to learn from the metaphor, and Richard Feynman agrees with him:

However, a question surely suggests itself at the end of such a discussion: Why are the equations from different phenomena so similar? We might say: “It is the underlying unity of nature.” But what does that mean? What could such a statement mean? It could mean simply that the equations are similar for different phenomena; but then, of course, we have given no explanation. The “underlying unity” might mean that everything is made out of the same stuff, and therefore obeys the same equations. That sounds like a good explanation, but let us think. The electrostatic potential, the diffusion of neutrons, heat flow—are we really dealing with the same stuff? Can we really imagine that the electrostatic potential is physically identical to the temperature, or to the density of particles? Certainly ϕ is not exactly the same as the thermal energy of particles. The displacement of a membrane is certainly not like a temperature. Why, then, is there “an underlying unity”?

Feynman goes on to explain that many of the analogues are approximations of some kind, and so the similarity of equations is probably better understood as being a side effect of this. (I would add: much in the same way that everything is linear when plotted log-log with a fat magic marker.) Huelsnitz, on the other hand, seems to behave as if he expects to learn something about the evolutionary history of the Corvidae family by examining crowbars ... which is simply asinine.
