Facebook is a Ponzi Scheme
Obviously this guy doesn't understand what a ponzi scheme is.  Perhaps if facebook took some of the money from new ad buys to purchase goods from slightly older ads so that they thought they were more successful a case could be made for it being a ponzi scheme -- this is in no way one.If in fact they are selling a defective or useless product then they are in the lemon business -- a card dealership that sells crappy cars will stay in business until everyone realizes they suck.Anyway, I've never purchased ads on facebook so this in no way relates to that; however, when you link to the definition of a word in your first sentence -- by god, use it correctly.
