This is a good point. How can we display feedback without revealing every transaction that happens for each vendor? And more generally, where do these measures fall short still. If you were trying to find out how big a vendor is, or how big the site is, how would you do it? Not sure I agree here. If you only know the percent, then you don't know the total number of vendors. I know we just made the switch, so you can make a good guess now, but if the vendor base grows or shrinks by a factor of 2 or 3 in the next 6 months, you won't be able to tell. It has always been this way.
