A common speculation, but I can't fathom how much value this adds to Google Maps, if any, what with street view and other 360 degree content they have at their disposal. I suppose that the crowd-sourcing aspect of it could serve to identify small sites of interest off the beaten path? Again though, what possible value does this provide to Google maps? Plus, a lot of the sites are already well known locations (churches) or are bunk (the "big red ball" out front of a local target)
