Kerning isn't the invented problem. The importance of marginal gains by adjusting kerning in logo design is. Imagine if I wrote an article where I was claiming that the blue component of the logo color should be 3% lighter. Maybe it's a real improvement. My concern is that the color of the logo on that scale is such a small part of what makes it a good design or not, that my reflex of analyzing it in that way is counter-productive to being a good designer. I'm not saying color is unimportant. I'm saying the focus might be too narrow to be used to do design.
