Boing Boing: Philly prepares to offer free WiFi citywide: "Philly prepares to offer free WiFi citywide
Exciting news in Pennsylvania today, after reports of many bureaucratic challenges -- Philadelphia has reached an agreement with Verizon that will allow the city to offer free WiFi as a sort of public utility. Free like liberty, free like beer."

This is excellent. I wonder which utilities should be free. What would happen if power, water, etc. were free, too? What is their motive? To get more tourists? More residents? To set an example, akin to Calif's leading many environmental charges? I like it.
