Disrupting Innovation

Every eBay member has a Feedback Profile, which includes basic information about the member and the Feedback that their trading partners have left for them. Learning to trust a member has a lot to do with what their past buyers or sellers have to say.
For each transaction, buyers and sellers can rate each other by leaving Feedback. Each Feedback consists of a positive, negative, or neutral rating, and a short comment.
Look at these feedbacks:

POSITIVE: Item shipped quickly, have been having erotic dreams about seller. Thanks!

NEUTRAL: Excellent communication, but should've poked holes in box before shipping the kitten. Refunded.

NEGATIVE: Despite indication in listing, I could not fit item into any of my body cavities.

NEGATIVE: The dog won't hunt.

NEGATIVE: Though you did nothing wrong, I am giving you this negative feedback to teach you that the universe is arbitrary and unfair.

NEGATIVE: Buying this Space 1999 Lunchbox did not fill the void in my empty life for as long as I'd hoped.

NEGATIVE: Honda R-Type sticker did not add horsepower as advertised.
