Probably referring to mine... which was rightly downvoted to the bottom because it didn't add anything to the conversation. Although, if that's the case, the GP should have been a reply to my comment, but anyway.

Since I can't edit that comment, I'll elaborate here.

The problem that I have with this isn't with "Reader". I just don't see how this has any benefit to Google. They aren't selling items. They are just delivering them. Does this go through some kind of Google online-mall, or will it go through the retailer's standard site?

The real question that needs to be answered is: what's in it for Google? What they've made clear lately is that for something to take hold, it needs to be in their interest. And I just don't see the upside here.

That's not to say I don't see a market for the service (I signed up to be a tester). I just don't see how it fits with Google.
