Media Mobilizing Project and local broadband activists are urging Philadelphians to call Mayor Michael Nutter on Wednesday May 21, to demand that the city step in to save the Wireless Philadelphia network and keep digital inclusion as part of it's agenda. Earthlink plans to begin dismantling the $17 million network June 12, after failing to convince either the city or a non-profit to assume ownership.
