Scott Lemon has been thinking about single purpose wi-fi networks for quite a while now. Today he sent me a link to Neighbornode, a special purpose wi-fi network in NY (mostly). A neighbornode is an electronic message board that serves everyone who can see it. In an area with dense housing, it creates a virtual community of the people who live near it. I like that its an example of a special purpose wi-fi network, but I also love that its a way to use technology to bring people in a community together.
