When Tony Guagliardo moved to Manhattan´s East Fourth Street, he didn´t know anyone in the neighborhood. Then one day, while trying to get wireless Internet in his apartment, he noticed an open Wi-Fi network named Neighbornode. He chose it, launched his browser, and a message board popped up welcoming him to the Fourth Street Avenue B Node. The network had been set up by a local resident who wanted to share his Internet connection. Soon, Tony´s neighbors were using it to discuss local restaurants, a community art project and even the block´s homeless guy, Eddie.
