You're kidding, right?
...that route put quality, reliability and privacy ahead of convenience...
Obviously written by someone who has never had to deal with the "quality and reliability" of city-run services in the Bay Area. If the City of SF is running this service, you can count on it being slower than snail-mail and about as reliable as Mayor Newsom. We'll get the customer service you'd expect from the DMV at lunchtime (motto: I'm busy filing my nails, but I'll get to that line of 500 people sometime today") combined with the efficiency of street maintenance (motto: "If we worked any slower, we'd be going backwards") and the convenience of the US postal service (motto: "We keep shorter hours than bankers")
At least Google and Earthlink are losing money if the network goes down. When a city-run network goes down, the city employees are collecting their paychecks as they lean on their shovels.
