Updating - was: [TCML] RF Grounding

Hi Bart, Richard, All,
    I agree that no author can (or should) be required  to change their 
documents. People who disagree should write their own. Now, if  an author desires 
to stay up with current thinking, they MAY feel compelled to  issue updates, or 
they may let historical documents stand as just that, a  historical document.
    The problem occurs when, with the passage of time,  pioneering works 
start to take on the mythic aura of scripture, and it  becomes difficult to 
separate what is best understanding from what was best  understanding from what was 
op/ed. One has only to look at the junk that has  grown up around Tesla's 
speculations, as well as his achievements, or consider  that many areas of science 
were held back for decades because "Aristotle  said...." was considered 
adequate scientific proof.
    Any document is partially out of date at the time  it is published. Of 
course, newbies and neophytes have the most difficulty in  separating what is 
still valid from what is dated, but that will always be  true. Keeping 
information up to date on the latest thinking through  iterations is, IMO, a major 
service that this list performs.

Hi  Richard,

I didn't state as I intended, but I'm one of those that would  find areas 
to update in the coilbld document. The problem I have with that  however, 
is that "my" opinion and other's opinions are not your opinions.  You 
should state your opinions as you see them. And if we disagree, we  
should state why. I can't see a few people on the list trying to update  
a document like this. If someone wants to update this document, heck,  
let them right their own document. If they want to update a program,  
heck, let them write their own program. It's very easy to criticize  
(especially on the TCML) and much harder to spend the time to create  
documents or programss. So, in the end, I say don't change a damn thing.  
I may not agree with everything, but so what?

Take  care,
