I'll echo a lot of the praise about the format of this post. It was fun clicking and watching the figures animate as I changed parameters.
I was sad that the author missed a number of chances to get into more detail about the classic reaction-diffusion problem [1]. I was reminded of a small project I did which produced similar animations, though with periodic boundary conditions, for learning about the Gray-Scott model. These websites are pretty helpful [2][3].
I haven't ever taken a class on systems so I don't know, but after reading this I wonder if the propagation of "scientific bullshit" and "truth" through a network can instead be modeled chemically as in a reaction-diffusion model. The last figure shows real knowledge fizzling out because it turns fake. It also lacks a slider so I can't play with the parameters but there should be some point where they oscillate back and forth, i.e. a Hopf bifurcation or a Turing bifurcation. Adding a bit more complexity might add some more depth to this post. I hope there will be a sequel!
