Having an interesting learning experience today revisiting mapping objects and relationships using active record in Rails 3.
I had an idea last night to create a new version of ecology mapping in the context of buying services or using shared resources. This is better than a "score card" and can be used for p2p/open source, carbon/climate change, local economies, commons and anything else you can think of. I chucked the idea of creating a survey and am going with this instead.
More on all of this later.
