A variety of sweet-potato, generally squat and brown, though some varieties are a reddy pink. They are a traditional staple in many parts of Africa. They are supposedly delicious when baked with a hint of brown sugar.

Personally I find them to be disgusting. I chose this handle with the same careful degree of consideration that I chose my other handle, Happyfish, which is to say, it popped unbidden in to my empty, empty mind. Everything is to blame for this too; it wouldn't let me register Happyfish despite there being neither a user nor a node of the same name. I can only assume that there exists a vast conspiracy involving blockstackers, myself, and an enormous vat of yeast. (I'd explain, but surely the inductive reasoning involved is too complex for human comprehension. It certainly evades mine.) I can only hope that in choosing Yam I have in some small way contributed to the demise of this foul plot. Or to its success. Either way would be cool with me.
