That's helpful. To look at the copycatting issue, which has been referenced as well, we had, many years ago now, at the international committee that had been looking at big data and privacy, Amazon before us. This came up, and they indicated they don't look at the sellers' data per se, but they can obviously get at the same data from the consumers' perspective. Is there not a concern when you have the large monopolistic player that has access to all of the data that is then able to compete?
There are different competing considerations. On the one hand, it does drive the price down, presumably, but on the other hand, it almost unquestionably hampers innovation. How do we square those two objectives?
