The worst thing they ever did was allow coders to do design work. The result is a lot of coders running around calling themselves web designers when they don’t know anything about design at all. All of the horrible websites out there were designed by coders. Web programmers, definitely. Web designers, definitely not. If this book helps at all with that, good deal.
In fairness, all the sites out there that don’t function properly were made by designers, not coders : )
