I think the DataMarketplace is a great idea. I wonder if quality or customer satisfaction will be an issue. I imagine there could be some datasets that don't quite meet up to the expectation of the buyer. But there isn't a real good way to refund money since there's nothing to return. For example, how do you verify that the dataset really contains 'Every Target Store' in the US? Perhaps they have an ebay-like seller rating feature planned?
