That is true but the fact remains. One has to pick his material a little better, otherwise he starts to look like a fool. I have no problem with what you did in the fact you got your idea from a blog or blogs. The problem was the article you wrote was filled with conjecture (the BK) and total falacies (the loss of 2 million subs) based on what, bad math skills and lack of information. Next time try to remember the gross retail adds.
P.S. Finally as a bloger, I dont think most would give a rats ass about credibility. As a journalist you put your credibility on the line with every article you write. You just lost alot of it with that article.
