"How meaningful is a SCORE when every BUYER ONLY will be virtually, at first glance, the same?"
Quite correct. Feedback for buyer is basically meaningless.
Most other online commerce do not rate buyers. Either they pay or they dont. If they repeatedly dont, they lose their buying/bidding privileges and are suspended.
On the other hand, it is important for buyers to see what feedback has been given to sellers before they send them their hard earned money. Sellers with above average reputation will attract more buyers.
