Let's take a step back and look at the bigger picture. Karma is not an 'excellence in engineering' award, nor is it a voting mechanism. Also, what you are suggesting is even more dangerous - someone 'higher up' classifying apps into 'worse' and 'near perfect' is basically a call to halt all innovation. Let developers scratch their itches the way the want to (within platform recommendations), and let people say what they think of those scratchers (+help improve them). As easy as that.
