Confused by Seth Godin

Internet guru Seth Godin is a smart guy, I'm told. And I've got no reason to doubt it.

But this post by Godin, The worst feedback is indifference, struck me as funny.

In it, he says that those who generate social media content, like blog posts, shouldn't dread "the cutting remark, the ad hominem attack." "No," he says, "the worst sort of feedback is no feedback at all. That means we've created nothing but banality."

But if feedback is so good, why doesn't Godin's blog allow for comments?

I'm confused.
