Alex Pooley reminds us that people really enjoy seeing their name (and hearing it as well).
Your name is the simplest, shortest way to be involved. Spammers have figured this out, but it still hasn't diminished the pleasure people get in hearing their name. I even smile when I get email from someone else named Seth
Infinitely customizable short run printing makes it possible to create color images like this one. No doubt that this tactic, like all others before it, will be abused and eventually lose its luster. Until then, people love seeing their name in lights, especially if the message that goes with it is authentic.
