Www may stand for World Wide Web but it could as easily stand for Wild, Wild, West given how there’s no agreement among writers, stylebooks, and glossaries about how to format its lingo – what to capitalize (listerv or Listserv or LISTERV*), what’s one word or two (home page or homepage**), and what has periods between letters (URL or U.R.L.***). So until the day arrives when we can all hold hands, sing “Kumbayah,” and agree that it’s e-mail not email, it’s probably easiest to use AP style and follow the exact formats below (it’s Ethernet, not ethernet, etc.)
AP, while a valuable resource in these matters, can be a pain in the ass, too, because once it decides a word or phrase is commonly accepted, it sometimes fails to include it in new editions. So “blog” was in the ’05 edition, but not in ’06. The word “wiki” isn’t in any print edition that I can find, but is located on APStylebook.com. So save this list because you won’t find it again all in one place! Lastly, AP uses quotation marks around blog titles (“Word Wise,” “The Sartorialist,” “Micro Persuasion”) and video game titles (“Wii,” “New Super Mario Bros.”) and, should you ever have to refer to more than one computer mouse, it’s computer mice. Eek!
I could find no AP reference to the following so I suggest you format like this:
* AP Stylebook (listerv), New York Times Manual of Usage and Style (Listserv), Webster’s New World Dictionary of Computer Terms (LISTSERV)
Note: I started the first sentence in this post with three Ws in a row – gheesh, it looks awful, doesn’t it? In any case, even if a word is lowercase normally, if it starts a sentence it’s got to be uppercased. (“I love my iPod. IPods are easy to use.” That, at least, is AP style.) (On a related note, when referring to people who in their own life format their names unconventionally, you must still format it according to accepted style, so though e. e. cummings carved out his artistic niche with a devil-may-care attitude toward capitalization (“suppose Life is an old man carrying flowers on his head...”), to us he’s E. E. Cummings. Ditto “k.d. lang” (K. D. Lang).
