What feedback, exactly, did Blockbuster ignore that caused them to go under?<p>The article doesn't seem to actually <i>show</i> any examples of missed feedback. There are some generic things about Apple being good and thinking of things other people didn't, but not concrete examples of customer feedback being missed.<p>Furthermore, I'm sure there are examples of companies following customer feedback and it <i>making things worse</i>. JC Penny and their giant discount sales, perhaps? There are no examples of that in the article.<p>Just seems short on substance, basically "feedback is good".
