Definition of blog

When asked by a reader to define what a blog is, Ed Kemmick of the Billings Gazette responded:

Have you seen "The Fellowship of the Ring," the first part of the "Lord of the Rings" trilogy? Do you remember when the good guys are passing through the dwarves' subterranean digs and that big green monster comes up out of nowhere and tries to kill everybody with a massive club? He is a blog. The name was borrowed to describe any Web site in which a grotesque, insensate creature wildly bludgeons everything in sight.
