Noah, I was simply responding to the part "what's the best way to test an application" in that once you release it, your users inevitably find problems, no matter how well you feel you tested it yourself.

Now, that's not to say that I recommend that you release code that you've barely glanced at and "feel good about" instead of testing. Testing is key, for sure.

But in the end, users always manage to find ways to muck it up. =)
