The new feedback system now makes feedback for buyers meaningless.
They should just make it so sellers can't leave feedback at all since
a buyer's feedback no longer tells you anything.

It's like the Model T or the 500 phone set, which came in any color you
wanted, as long as that color was black.

You can leave any kind of eBay feedback you like for buyers, as long as it
is positive.
