It's amusing how much time the guy has devoted to writing about things he knows 
little about. It would be a bit like me writing about brain surgery, concrete, 
glues, flower arranging, or anything else I know next to nothing about.

Reading his background notes, it sounds like he knows a lot about welding. His 
time would be better spent writing web pages about that.

I have an electronics background and try to not be overly critical of people 
that do not. But when they go writing web pages, as if they are an authority on 
the subject, it does get a bit annoying.

It is like the Wikipedia article on the Yagi-Uda antenna. Clearly written by 
people that know next to nothing about them.
