word of mouth: very contestual.
The brilliant Word-of-Mouth guru Andy Sernovitz is having a bit of a contest. It's pretty simple, too. Just go here, and send Andy your stories of great word-of-mouth campaigns. The less money spent, and the less corporate they are, the better. And, if it's good, you'll get a free bottle of Avalon or Capolan wine. If you're not eligible (like you Austin and Max), then he'll send something else. Like maybe a hat or a coupon for free french fries. Do it!
