According to PC World:

EarthLink next month will shut down its Philadelphia Wi-Fi network, the flagship of its now-dashed municipal wireless initiative, and then remove it from the city’s street lights.

It’s sad to hear this, means that yet, Muni Wi-Fi, is just a dream and no one found a model that works. What I want to know is, WiMax is trying this same model, what’s gonna be different? Why is it going to work?
