MindMixer.com is a new web app + service designed to act as a “virtual town-hall” for municipal engagement.

Its a US base company marketing the tool specifically to community leaders and elected officials. Seem like a cool tool, although I’d assume like any open invitation approach (including traditional town halls), the prioritization of ideas is open to manipulation through strategic online campaigning by large groups.
