The hyphen just got slightly more obsolete, and you just saved yourself a lot of right ring-finger reaching. In a move that feels so right it surely should've been made years ago, "e-mail" has been deemed incorrect. From now on, we send emails.
The move will be officially announced at ACES 2011, with the change going into effect tonight. Why is this such good news? Because language is catching up to technology. Because those videos of animals riding slightly larger animals you forward around aren't just "electronic mail" anymore, digital versions of what you stuff in a dark blue mailbox. They're now a form of communication unto themselves. I mean, they always have been. But now it's AP-official.
You're welcome, of course, to continue typing "e-mail" as much as you like. You're also welcome to make popcorn over a fire pit, or ride a horse to work. Email is the future. And e-books? You'd better be next. [Twitter]
