Here are my two cents on quality score:

Penny #1: It's like your credit so watch it carefully.  If you let your credit score slip, it is very difficult and it takes a long time to improve.  With your bills, missing payments on one account will have a negative effect on your credit score. Quality score is similar in that it only takes one bad keyword to effect your entire campaign.

Penny #2:  Quality score effects the cost per click of your keywords and the position your ads are placed by Google's search engine.  Did you know that someone with a higher quality score can bid less and still show up higher on the page than you.
