Certainly the wider the audience or the more controversial the subject, the more care I'll take in composing and checking the email. However, I can't say I delay the sending of potentially inflammatory emails, since I don't tend to use email as the preferred medium for that kind of communication. If I want to get angry with someone, I tend to pick up the phone or wander over and talk face to face.

I'm just a great believer in public praise, but private criticism.
