Last week, the New York Times ran a side splitting story about people who send emails or texts while under the influence of alcohol (Drunk, and Dangerous, at the Keyboard).
Funny, but true, we can wreck our lives over email if we've been drinking! In the study behind The Dirty Dozen Rules of Email Etiquette (an excellent program to bring into your company), we found that grammar and syntax errors jump almost 50% when users send emails after having a single cocktail or a few beers. Their use of profanity jumps too.
The lesson: Never assume you can master email while tipsy. Much like driving, alcohol will give you a false sense of security.
