As true as this is, hiding the "www." subdomain isn't the right solution. For starters, it doesn't work for non "www." subdomains, for example... news.ycombina

As true as this is, hiding the "www." subdomain isn't the right solution. For starters, it doesn't work for non "www." subdomains, for example... news.ycombinator.com isn't protected by this solution. A better solution IMHO, would be to do it like firefox, grey it out.
