It's good when it works, so that it helps you do what you gotta do. It's fun when it adds an extra dimension to your life, like greeting cards with songs and animation. And it's even more fun when lots more people than usual know it's your birthday, which happened to me the other day. Besides getting the good wishes on Facebook, I also got to see them as they came across my iPhone as both text and emails. Treble good wishes can't be beat!
