The SF Gate reported Friday on chummy interactions between Google's founders and San Francisco mayor Gavin Newsom: Nothing untoward was found, the newspaper reports, but there's a quite close relationship. The mayor is isolated from the decisionmaking process that will pick a winning firm to build SF's Wi-Fi network, with the winner bearing all financial cost and risk. The article looks Newsom's relationships and friendships with a number of high-profile Internet firm founders and executives, but there's no smoke nor fire. It seems like a good example of public accountability: the mayor's office seems to have handled numerous contacts well and the arm's-length relationship of Newsom to the Wi-Fi decision seems appropriate. The public disclosure that allowed the San Francisco Chronicle to obtain emails relating to these relationships also worked in this case, according to the story.
