Thanks Dave, good explanation. I was looking up HF topics and saw how
high frequency tends to make the electrons move only at the of a
conductor. The wider the conductor the more edge it has so the less
impedance it presents to the current. Pretty cool concept really!
I also hadn't thought about using the grounds as shielding against RF
from other traces. Makes sense once pointed out though I guess. I'll
have to try that on a noisy board and see what kind of difference it
makes. It'll make routing an even bigger hell than usual though :X
