A lot of people are attacking the article, but aren't really engaging with its central point:
If you run a bricks and mortar business, you don't need to notify people to tell them that you've redesigned your website. Your customers are probably not interested in your website, except as an analog/support for your core business. If the redesign makes their life easier, they'll notice. If not, they probably won't care. In either case, they'll find out soon enough.
