I've been curious about how to pay people for their datasets.. I feel like research into that is really interesting.. what would be great would be if you could essentially pay known trustworthy sources for vetted data, and those sources would essentially crowdsource the data by literally pounding the pavement or parsing through difficult to parse datasets.. I mean entire businesses are based upon that, so I could see how this gets out of hand quickly where somebody wants access to a dataset but does not want others to have access to it. But anyway, I wonder if people have studied the "how to pay people for datasets" problem where you get good quality data that is not gamed to just be maximizing profit, but at the same time people have an incentive to collect the data.
