Ken Rockwell laughing stock.
I think you fell at the very first hurdle here. Ken is well known by photographers as a very very hit and miss site. He was an engineer so knows quite a bit about camera production, however he does not know about photography. Be very careful when reading his site as many of his ideas are incorrect and may not be obvious to the beginner. For example shooting in JPEG, because he always gets it right in the camera very misguided.
A quick search will show you that he is not loved by all. https://www.google.co.uk/webhp?sourceid=chrome-instant&ion=1&espv=2&es_th=1&ie=UTF-8#q=ken%20rockewell&es_th=1
