Minneapolis is testing a fresh new approach to gathering public input. Frustrated by low attendance at public meetings, it has launched its first wiki -- an online format that allows users to change the content of a document. The new wiki allows residents to tinker with the city's 2008 comprehensive development plan. To participate, individuals need only go to the bottom of the page, click "Edit," and type over the old text. The changes are saved and allow city officials to look through the history of revisions to see a spectrum of input. The wiki was launched Jan. 5, and will remain open until the plan's 45-day draft review period ends Feb. 16. If the pilot site, hosted by the Minneapolis chapter of the American Society of Landscape Architects, gets enough well-thought-out contributions, it may be expanded to other planning forums.
