I've often wondered why Web addresses shown as ".com" are called DOT COM rather than PERIOD COM or even more correctly POINT COM.

Les heard my giving my telephone number on a message and he asked, "Why do you say 0 in 5-0-5, but say "ZERO" in 6-ZERO-x7?" I didn't realize I was doing it that way, but since he brought it to my attention, I am self-conscious about it now and invariably make a mistake. I should be British and say ZED!
