A question: as a non-american, in view of America's current levels of paranoia, does this really have much potential beyond, say, bike-racks and street-lines?
I'd love to know, for example, which areas are served by fibre, which have a high numbers of wireless communication towers, which are serviced by new (as opposed to ancient) utilities? I can imagine some bureaucrat deeming many game-changing datasets as "security risks".
If that's true, then what's left to publish?
I'd also like to know, what commitment is there to keeping datasets updated? My guess: GitHub makes this much easier. For example, how long before hundreds of privately owned bike racks get added? How long before pathways get crowd-sourced into the data?
