What's the fuss about Credit Score / History?
Since we seem to be discussing credit score and credit history interchangeably, if I can add credit report as the third part of the puzzle, I have another point. Your credit score and credit report can be effective tools to notice identity theft or fraud in your name.   Keeping track of your report will allow you to not only protect your good name (which is apparently in dispute here) but also those businesses who ultimately end up paying for the stolen goods or services.
