In my opinion, a very misleading and useless list. It has never been very helpful to list coupon codes because they have very short expiration lives.
I also don't believe that anyone here is that much of an authority that they can reliably "rate" and put their stamp of approval on hundreds of discount codes. I have had personal experience with several of the codes on Sam's list and I totally disagree with many of his "ratings". I'd much rather recommend that people read more of the posts that are code specific and chooose their own "best code" rather than rely on the ratings of some self-appointed "authority". Perhaps i would feel differently if each code rating had a reasonable explanation why it was rated as it is (good, great, ok). But that would require actual knowledge instead of just idle time.
