I'm so glad I read this article because I was watching a commercial last night and wondered about this exact thing. I've been so happy with Wordpress and any questions I've had, I've been able to look up and figure out myself. I didn't want to have to spend a ton of money for a marketable theme/product/design, but it isn't really that big of a deal in the end. I think I also lack the graphic design skills to make something look visually stunning.
