Unfortunately that isn't true.

The number of people viewing something one way with unscientific methods (my 
xxx worked great and made more contacts than any other xxx I had) another 
never determines what answer is accurate.

Often the most repeated and simple answers, or emotional answers, are more 
often accepted.

How something works is never settled by popular vote or argument, or by 
blind faith. It is settled by known physics and measurement.

In this case anyone building an antenna from twin lead and writing an 
article could (or should) have taken the time to actually measure a folded 
dipole. had they done that, they would find resonant frequency does not 
change a measurable amount when the dipole goes from regular dipole mode to 
folded dipole mode.  This clearly means the velocity factor is not a 
measurable factor in the system and shorts are not needed, because there is 
no resonance shift when operating folded or parallel modes.

The real problem is we have data based on assumptions or feelings without 
verification.
