eBay is a great example of a feedback system with different expectations than a naive user might assume.
I used it mostly when you had positive, neutral, and negative. One might think that taking a few extra days to ship something or an item not being in quite as pristine condition as advertised was probably a good candidate for a neutral. Not bad/not perfect.
But that wasn't really the expectation. Neutral was more like "It took me two weeks of emailing but I finally heard back from the seller and they shipped the item which really wasn't as described but I just wanted the transaction done at that point" Negative was "They shipped me a box full of bricks and made me pay the postage."
