In the beginning, everyone referred to the place you published your web site as "World Wide Web". Once we got better aquanted, we used the nickname "WWW". Using the web is now so comfortable and familar, everyone knows what you mean when you invite them to "visit my site". That's why I can tell you without fear of contradiction that the W in "www " is silent. You don't need to use it in print, or when you say it out loud or even when you type it into the address bar of your web browser. If I want to invite you to my site I simply say "Visit MakeTechnologyWork.com" I know your skeptical, so prove it to yourself. Launch your web browser, click in the Address Bar and type your domain name and press enter. If you end up on your site, great! You can stop stumbling over the "www" when you say it aloud and you can finally get it to fit on your business card. If it doesn't work, and you find the www is required, contact your web professional ask them why. It should be a very interesting conversation.
