Being a web developer, I feel the need to comment on the common practice of pronouncing www when speaking of a website.

There is no need to say www when mentioning a website.
Just say, “Please visit my website at widgets.com.”

There is no need to use http://www or even www when typing in a browser.
Just type gadgets.com in the address bar and you will be shown the site.

There is no need to use www in print advertising. It only gives the reader more to read and memorize; especially a problem on an Interstate highway billboard.

Browsing for buywigglyworms.com is the same as BuyWigglyWorms.com. Uppercase is only used by advertisers to make it easier to remember.

When purchasing a domain name be aware that choosespain.com can be read as both Choose Spain and Chooses Pain, to use a G-rated example.
