The short answer? Everyone wants in Google's experimental 1Gbps fibre optic network(s). The company received "1100 community responses and more than 194,000 responses from individuals" after announcing their plans. And these requests span the entire US.
(Each small dot you see on this map represents the response from local government. Each big dot represents communities with over 1000 respondents.)
Some may see this map as people hungry for fibre; I just see it as people hungry for Google. How many communities would beg big businesses like Walmart to set up shop, not just in some lot, but in their very infrastructure - especially knowing that whatever service there is will be in beta? [Google]
