I'm just pausing here for a moment to reflect on the poor, sad bastards from the original, post-inspiring Facebook page who imagine going to live on a commune or off-grid community is actually *less* work.
Now... gardening, (which is not farming, which is critical for a truly self-sufficient off-grid community), vegetable canning, herbal preps, sewing, cooking, basic knitting. Natural dye experience, willing to work occasionally with urine on windy days. Good work ethic, likes to learn. Sing, play quitar.
I wonder how many people you'd actually need to be sustaining in terms of your own cloth, food, water. Glass making. Medical personnel.
