Should Developers Listen To All Gamer Feedback?

Thanks to GameSpy for their 'Spy/CounterSpy' editorial discussing whether the videogame developer should listen to all fan feedback regarding in-development titles. The writer suggests: "Who in their right mind ignores advice from the people who are going to pay for your product? And in the end, that's what it comes down. Fans pay the bills - and they deserve respect." Bit he also points out the negative angle: "Fan suggestions are usually what would make the game better for that one individual. Developers need to consider the global effects of any suggestion and work to keep the majority happy." Are there some game titles or genres where a vocal minority's agitation for change has resulted in an inferior title?
