Jimbo's role seems to be that of a strange attractor. His actual amounts of a) power, and b) influence are significant but limited. Like the planet Jupiter, he doesn't have enough gravitational pull to assemble things into an arbitrary pattern through brute force.

But he seems to have an intuitive understanding for the interplay of forces governing Wikipedia's chaotic behavior. He can detect the places where things are in a delicate unstable balance, so that pushing on it will actually have a lasting effect (rather than a tiny shift and a return to equilibrium once the force is removed). And he even can guess what the general effect is likely to be.
