Ooh, Wired Style: Principals of English Usage in a Digital Age appears to have been reissued and updated (at amazon.co.uk or amazon.com) on 28th December 1999. Unfortunately, looking at the reviews, this doesn't seem to be what I'm after. It's a glossary of modern terms (like 'email' with/without the hyphen, and the plural of 'mouse'). What I wanted was a guide to writing for the www: Single-topic paragraphs, differences from daily newspaper writing, that kind of thing. I'll have to take a look at the book before buying it.
