A few years ago, I mentioned the domain name for one of my Web sites to a friend of mine. “Go to itotd.com,” I said.
My friend looked puzzled for a moment, and then tried to correct me. “You mean www.itotd.com, right?”
“You don’t need the www-dot part,” I said. “Just the domain name.”
My friend was completely baffled by this statement. “But I thought all Web sites began with www. Isn’t that required?”
Now we were both baffled. It had never occurred to me that someone would think this, and it had never occurred to my friend that someone wouldn’t!
