I added these links to our link section in the right column, but wanted to note them explicitly. One of the goals of this site is to catalog what groups around the country are organizing for better networks that put the community first - if you know of groups, please let us know.
In California's El Dorado County, the Camino Fiber Network Cooperative is seeking ways to finance building broadband to people who currently have no options. Thanks to Eldo Telecom for tipping me off.
In Massachusetts, many communities in the western half of the state have no or poor broadband access, which is why Wired West is investigating options for a publicly owned, open access network.
