The philosophy and culture of bug reporting:

1. A bug is any unexpected interaction between you and a product.

2. A bug report offers you an opportunity to troubleshoot a problem. Ideally, it results in a solution before even being filed. Otherwise, it is a recipe for the developer to experience the same problem as you have.

3. Bug reporting is collaboration. When you file a bug, you are not disturbing the developers, nor are you exposing them as poor or nefarious programmers. You are developing along with them in an attempt to optimize an application you love.

4. A good bug reporting tool is also a task management tool.
