I learned that a "cute" message can be the best thing. I am a dev on a top iPhone app and while testing our push notifications, I sent a notification out to millions of people. Luckily I wrote "Have a nice day!". It cost thousands of dollars but our vendor was nice enough to refund. In my case, people thought we were just trying to cheer them up. Had I wrote "this is a test", people would have been annoyed and lost confidence in us.
