Personally, I'm a fan of Dillo dirt for lawns and ornamental use, but not vegetable gardens, because it's made from human feces and mixed with lawn trimmings, among other things. Yes, I know it's composted, "cured", and that all the pathogens are dead. I agree that it's safe and I'm fine with having it in the lawn, but I'm not going to grow food in it.
You've got to draw the line somewhere, and growing food in my own **** (and that of my friends and relations and ex-girlfriends and so forth) , composted and sold back to me is right there.
