FWIW, the cited pages were not Usenet threads.

There are several purposes for grounding and they are not all served
in the same manner.  Shielded cable is often grounded at one end
only.  Electrical safety grounds are typically grounded from the
exposed metal components all the way back to the breaker panel and
from there to the ground rod.  Multiple services within a single
structure should be connected to a single grounding conductor or to a
bonded ground system.  When multiple buildings near to each other are
interconnected, use a bonded ground or isolate them.
