Your critics are never going to be happy with you, that's why they're critics. Changing your act to make them happy is a fool's game.
Here's a surprising thought, though. You should ignore your fans as well. Your fans don't want you to change, your fans want you to maintain the essence of what you bring them but add a laundry list of features.
So, who should you listen to?
You should listen to the people who tell the most people about you. Listen to the people who thrive on sharing your good works with others. If you delight these people, you grow.
So I guess I'd be one of Seth's sneezers... :)
