A lot of applications that I have worked on (primarily written in PHP) use Exceptions in a fashion similar to what has been shown in the example. And, I have seen places in code where exceptions get thrown when there is no data in a given table instead of returning zero or null. But, the I wouldn't be totally against using Exceptions in the example on that page if the calling method does something very important. I would love other's views on this.
Also, I was able vote multiple times for the same example (went from -3 to 3).
