Only in the last weekend (while reading a very informative article in the New Yorker about Al Qaeda's internet operations and its role in the Madrid bombings on the plane) did I notice this strange journalistic practice: "w" of web site is capitalized, as in "Web site". Perusing the LA Times and the NY Times later on confirmed this practice, and I can't make sense of it. Is "Web" still considered a proper noun, a shorthand for "World Wide Web"? Seems to me the language so ingrained now into 21st century English that it should be in lower case.
Anyone have an explanation for this strange grammar rule?
