Godin on how to give feedback

I'm a big fan of marketing maverick Seth Godin. His provocative post today on feedback initially took me aback:

I don't want to know how you feel, nor do I care if you would buy it, recommend it, or use it. You are not my market. You are not my focus group.

But when you read the rest of the post, his comments not only make sense, they'll probably change the way you give -- and ask for -- feedback.
