You may have noticed a new icon on the sidebar of this site linking to the No-www.org site. It’s something I was recently told about by a friend (the admin for the Lunarsoft website and forums) and once you think about it, makes perfect sense. The WWW mindframe came about back when the web was growing, and becoming more familiar to all of us, but actually represents a subdomain of your main domain (in my case, zxian.org). This subdomain look up requires more work by the servers that send you the website you’re seeing now. This added work means that the site lookups are not only slower for you, but for all the other people accessing that server.
Go ahead and remove that www from your websites. You can do this with a simple .htaccess rewrite rule as described on the No-www website.
