www. is deprecated.: An effort is underway to remove the “www” from site addresses. If you do, you can get a little badge to display on your site. I agree with this — it’s an idea who’s time has come.
By default, all popular Web browsers assume the HTTP protocol. In doing so, the software prepends the ‘http://’ onto the requested URL and automatically connect to the HTTP server on port 80. Why then do many servers require their websites to communicate through the www subdomain? Mail servers do not require you to send emails to email@example.com. Likewise, web servers should allow access to their pages though the main domain unless a particular subdomain is required.
