Opponents of publicly owned broadband networks often hold up examples of wireless networks that did not turn out as planned -- more often than not, they ignorantly use examples of privately owned networks like Earthlink networks in Philly, Houston, or proposed privately owned networks in San Fran and Chicago.
It is true that many wireless networks (especially those using Wi-Fi) came in above projected costs and late. It is also true that this happened across all manner of network ownership types. GoMoorhead, a publicly owned Wi-Fi network in Minnesota, was recently sold to a private company - and I am working on a report about that. However, there was also a recent announcement that the privately owned wireless network being built in Burnsville, Minnesota, is behind schedule.
