I like this idea. It doesn't speak much of self-sufficiency, but does speak to several issues at the heart of the self-sufficiency movement. Since it is allegedly already on Facebook, I assume it might reach a wider audience than here, but I guess every little bit helps to spread the meme.
Please copy, paste, link and quote. (I've taken some liberties with the wording; the intent remains the same.)
