Ed, good points in this article, and the second one is especially brilliant. One of the hardest tasks I have is getting my clients to see things from THEIR client's perspective, and to address their client's experience or what they want to experience.
That said, Cassandra's tagline intrigued me and combined with seeing that she's in my town, it compelled me to click her name and find out about what she does. Since I happen to be in the market for a facial, I'm delighted to find that this is one of her services, and am further excited to see that she's about 3 minutes from me! I'll be making an appointment with her today.
So there's something to be said for a tagline addressed to how a client base sees themselves that works on a local level for the service you provide.
