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. The response has been remarkable, and non-technical people can think about it like an effort to work together on a living dictionary for the food system; food names, methods, practices, terms, and definitions that the geeks can go to when they build their apps, rather than re-writing their own version.
