Not true, Bob. Indeed, it is a critical component of lightning 
protection, which is why it is required by electrical codes. So is 
bonding. You are, however, entirely correct that an earth connection has 
to relevance to hum, buzz, or RFI. Was it Bill or Neil that so 
poetically said that earth is not a sump into which noise is poured? I 
have often used that quote in my talks and writing. It is, indeed, the 
bonding that is critical for that as well.
