Open-Food.org: Worldwide collaboration to improve food apps.
Forums:
Within the tools/apps wiki I think it'd make sense to make sure the group's aware of the Open Food Data movement. It was launched at South by Southwest in a collaboration lead by Foodtree, Food+Tech Connect, CleanPlates, WindowFarms, and the support of many others...it's a collective effort to open source food data standards so that app and tool builders don't have to reinvent the wheel.
