Wired News has a nice article about how Muni Wifi is helping low income residents in San Francisco get wired:
Last month, volunteers turned on a novel broadband network in this 135-unit block, throwing a digital lifeline to Emma Casey and other tenants. Using a refurbished PC she picked up for $100, the 47-year-old mother of two adult children is now going online to help her son find a job, get health information and, she says, pay tribute to neighbors who've met with violent or untimely deaths.
