Calling it GROUND is simply WRONG. That's where the misconceptions come 
in. Signal paths must be a TRANSMISSION LINE to function properly -- 
reject noise and crosstalk, and provide sufficient bandwidth for data. 
Ideally twisted pair or coax. Not-twisted pairs will carry the signal, 
but have poor rejection of noise and crosstalk (and generator whine is 
noise).
