just hit "send"?

While I'm on the topic of technology, I'll encourage you to check out this article about "Send: The Essential Guide to Email for Office and Home." It's a new book about "e-mail mistakes and how to avoid them." The book's central focus lies in the way in which the "Send" button often promotes impulsiveness and rash emotions. And, in turn, disasters.

The article notes, "We imagine it (e-mail) as a casual private message that vanishes into the ether. In fact, it's likely to be far more permanent than any paper communication. E-mails can be stored with ease by the recipients and by third parties, such as the corporations from which they are sent."

The book, basically, is an etiquette guide...addressing everything from why it's not cool to address your professor with "hiya" in an e-mail to the implications of Britney Spears' 2006 decision to dump K-Fed via BlackBerry.

Do e-mail manners deserve a spot in book retailers' shelves? Absolutely. Take it from the girl who was dumped via a changed relationship status on MySpace. Do you think technology will ever progress to a point where that kind of breakup is not only expected, but accepted?

What's the biggest e-mail mistake you've made? What, if anything, would it take to get you to circulate a once-private e-mail out of rage?
