Slogans used to be important because you could put them in TV commercials and get your message across in just a few seconds. Today, that same conciseness is important but for a different reason. A slogan that accurately conveys the essence of your Purple Cow is a script. A script for the sneezer to use when she talks with her friends. The slogan reminds the user, "Here's why it's worth recommending us; here's why your friends and colleagues will be glad you told them about us." And best of all, the script guarantees that the word of mouth is passed on properly - that the prospect is coming to you for the right reason.
