I draw the line between feedback and advice.<p>Advice is worthless, feedback is priceless. Advice is a user saying, "Holy sneakers, I just thought of the biggest idea for how you can make a social networking online publishing app!". Feedback is a user saying, "I keep clicking this and it doesn't work" or "does the site do x?". Big difference. Advice, even good advice, is easily come by.<p>Feedback is a whole nother animal. Feedback is the voice of the capitalism speaking through your users.
