As Kim speculates, it may be us 'small guys' (now one might take offense there😀 ) who are less likely to be retaliatory, and provide a more considered feedback, but I bet we all have a few 'regular' phrases that crop up in the feedback we give as buyer or seller. How many ways can one say "Great transaction" or "Excellent Communication"?
My main concern is that the feedback system will no longer be of the same use to a seller as it is now when dealing with folks who are asking questions. I really don't want to spend my time figuring out how much it will cost to send something to Kucamunga for someone whose feedback shows them to sometimes be a PITA to deal with after their payment is sent, but for someone with 100% feedback that shows them to be a 'straight dealer' I will. I pick who I buy from this way as well. Just like picking the place you buy your gas, if one has friendly clerks and the other has jerks I'll go to friendly.
