If you type google.com or facebook.com into a web browser, you're redirected to www.google.com and www.facebook.com respectively. nasa.gov doesn't even resolve and you must type in www.nasa.gov to reach their website. I've read up a bit on the history and preferences regarding the www subdomain, but what should we do now? If you're setting up a website in 2012, would you forward the naked domain to www or not?
