In 2004 we started the Davis Wiki, an experimental project to collect and share interesting information about the town of Davis, California, editable by anyone.
Today the residents of Davis use it for everything from learning about local news and local history to helping return lost pets to their owners — and it's become the largest, most used media source in the city. In week, nearly half of residents use the Davis Wiki; in a month, nearly everyone uses it. And 1 in 7 residents contribute material to the Davis Wiki.
With your help, we want to help as many communities as possible realize the full potential of such an amazing, collaborative information resource.
