As the first website to be demonstrated by a sitting President of the United States, Healthcare.gov already occupies an unusual place in history. In October, it will take on an even more important historic role, guiding millions of Americans through the process of choosing health insurance. How a website is built or designed may seem mundane to many people, but when the site in question is focused upon such an important function, what it looks like and how it works matter. Last week, the United States Department of Health and Human Services (HHS) relaunched Healthcare.gov with a new appearance and modern technology that is unusual in federal-government websites.
