Community think tank site

We need a community think tank that can work anywhere from any state or city in the USA to other areas. Similar to Craigslist it’s a place where people navigate to their area community on another new community site and discuss ideas that can be focused on in their areas and how to help make it happen either at the government, non profit or community levels even with their community organizer involved or anyone.This can over time be the influencer on how government can be better integrated and connected with their communities and their needs.

Something that can have a broader focus on individual cities states and or countries. Who knows, something could be adopted at the political from it.
