“The word “design” is a hard one to pin down. While it means many things to many people, one of the constants, as it relates to media anyway, is communication. When it comes to presentation, e-mail, your blog, invoices, resumes or anything else you use to communicate with others, a little design can be a big help in getting your message across.
I emphasize “little” because one of the most common mistakes when it comes to design for communication is over-design. You want to design for clarity and to add meaning or context, not to obscure your message.”
I came across this post today and thought is was just about the simplest expression of design as a principle.
