FSF Fact:
A normal steaming pile of poop if stacked correctly and nutured in the right conditions will quickly rot down into a relatively sweet smelling substance referred to as compost, widely used as a soil conditioner. The process involved in creating compost will also greatly reduce the volume of material that made up the original steaming pile.
It can clearly be observed that the volume of material making up FSF does not reduce nor does it become any sweeter smelling over time. We can safely assume as fact then that, despite a constantly plentiful supply of poop, someone isn't stacking it right and taking care of it enough to produce any useful compost.
Merely one of many amazing facts about FSF.
