I think community generation of data is a good thing, but community in and of itself isn't enough. I'm going to go out on a limb here and predict that, soon, any "community" enterprise that is not also a rewarding, multi-dimensional game will struggle. OpenStreetMap (for example) succeeds because it's full of good games: community building, sticking it to The Man, and winning respect in the industry are just the obvious ones. Are there any games worth playing at TeleAtlas? That's the crux.
