I'm aware of what color schemes do for businesses, I just don't think the way she presents these is valuable. I also don't doubt she's popular on pinterest. Websites like that and tumblr revolve around anyone who can provide aesthetic beauty because their traffic consists mostly of bored people clicking through pages and pages of stuff they won't remember tomorrow. I do it myself, but I have to disagree that this sort of content is valuable to a designer. It skips past the thinking and facilitates the clicking.
