A San Francisco Chronicle editorial asks the Board of Supervisors to show an alternate Wi-Fi plan: The editors think that with EarthLink on the hook, minor quibbles should be swept away unless the board has a viable alternative plan that wouldn't involve an "experiment" with $10m of taxpayer dollars. It's a tricky position. San Francisco has received about as good a deal as any other city its size. Portland, Ore., is the sole exception, with free 1 Mbps ad-supported service from MetroFi. SF rejected MetroFi's proposal, and it would be good for the larger Wi-Fi community to see different models built in different large metropolitan areas to see which one works best, or if they all work equally well or poorly.
