Personally, I have found BC's information to be very valuable. He has synthesized a tremendous amount of information on products about which little well-written information was available.
He, like all of us, has no doubt grown in his understanding and knowledge about gear and about how gear interacts with the human body--I am sure that alot of his writings are a bit out of date and that he, too, would admit that--but who among us would say that our thinking and knowledge has not expanded due to the interactions available to us on the Internet? I am quite sure that things that I myself wrote 5 to 10 years ago, in published literature, are now outdated.
Also, much of the medical literature has to be extrapolated to apply to the (novel) ways in which we utilize these precious gold oils. The kind of studies that WE would need will never be done (although you could sign me up for sure!).
