My first thought exactly. This could be epic for so many things that are not practical today. Maybe the incentive could just be: To get the data, you have to participate in creating it.
Would love a "how long are the lines at the nightclubs" task
Edit:
Maybe it's worth looking at how private torrent sites do this, there has to be an incentive to seed or it doesn't work. There's basically a ratio that can't drop too low, or a point system where you start >0. So you have to give X to get Y. Maybe let the users pay for "points".
