Except in headlines. Wired News has made the bold stylistic move of no longer capitalizing the ‘i’ in Internet. The casual references Web and Net will also no longer be capitalized. These kind of changes in style really only matter to crotchety editors like myself who still care about consistency.
For those really into style, it’s also worth noting that in 2000 Wired News made the decision to hyphenate e-mail. So there. (As every editor knows, the style debate is simply a more educated form of the old playground debate of who has more friends.)
