Regarding photo suppliers, people buy carbonate, borax, Metol and HQ among others. Some, such as the alkalis are bought in bulk and the others in much smaller quantities. It would be foolish to assume that Artcraft, B&S and the Photographers Formulary could exist selling only small bottles of developing agent. They must sell a well rounded group of photo chemicals or their profit will drop. I would imagine that if those who mix their own brews bought only the developing agents from such companies, these companies could suffer up to a 50% loss in sales.
Do you want that as an unthinking and unintended byproduct of your advice Patrick?
So, education is not enough for one to look at the consequences of ones actions and words. I have learned this well here on APUG. One must also gain wisdom. You are "fighting" for a position, but I am "fighting" for a future that I hope will outlive me.
As for being vetted, I have been well vetted at EK. If you think anyone can pubish there without lots of peer review, you are out of your mind! I have served as both the writer and editor in publication. The internet requires none. We get what we deserve, I guess.
