I think Bill is just trying to make a point that the name stinks, and I
agree with him. Yes the meaning is well defined and accurate, but the
term is misleading. Sure, it isn't going to go away. It's in all the
literature, and it isn't going to change, but the point is still that
the name is misleading. I have had to teach this concept for many
years, and invariably when someone hears the term for the first time
they think there is only one ground allowed in the system. I have even
seen this concept implemented incorrectly in electronic systems by
designers who read a little about it and never understood it, resulting
in requiring a total redesign for the system. Thank goodness those were
not my students.
I think most of the readers on this reflector understand the concept,
but when you look at the ham population in general, very few understand
it, and the name just makes it more confusing.
See, I still didn't say the correct name. I had to use it when teaching
about it, but I made sure everyone knew I didn't like it.
