I could spend all the hours after my kids are in bed reading posts from this site on permaculture. I would get months of solid learning from Paul Wheaton’s stuff alone: from rocket stoves (dvds on same), to energy savings, to homesteading, to raising chickens, pictures and post on the experimental wofati house as it develops, and on! It will continue to be a source for many more articles to come, I’m sure.
But don’t wait for that! Go over there, sign yourself up, and start learning from and interacting with all the good folks over there at permies.com.
