I Love this short piece and the turn of phrase “a bit of a forward rush” from Paul Krugman’s blog about why he uses elastic and informal language in his writing. I get flack for this too, as well as for using exclamation points and smiley faces in my emails.
Standard business language is unnecessarily tedious. If I’m using a smiley face or an exclamation point in my correspondence it’s probably because I’m genuinely excited to be talking with you about whatever it is we’re talking about.
Reference also If you’re happy and you know it, must I know it too? from Sunday’s NY Times (October 21, 2011), which quotes a bunch of cranky people who don’t like smiley faces very much.
