@viewmont - your response, in all those words from eBay, say the same thing I did. Feedback is an evaluation of a transaction, not a part of it, so my question remains unanswered. (If everyone was so influenced by what eBay said was important, there wouldn't ever be any NPBs, shonky sellers, crude user names, disruptive forum posts.... The list goes on).

Maybe I should put this another way, and this goes out to the buyers that get angry etc if they don't get feedback for a transaction. For argument's sake, let's say eBay abolished buyer feedback.

What do buyers feel like they would miss out on?

I would like a genuine answer from anyone that feels like feedback is an integral part of the transaction.
