Poor leadership, flimsy/parasitic business model, lack of long term engagement path for users, chasing trends rather than creating them, PR failure.

Zynga is a company that is that high school most popular jock that hops in front of all others and excels based on a small advantage in physique and looks and personality and bullies the others out of the spotlight only to be the 20-something failure who is realized as having stole al their charm from observing others' talents and mimicing them - and ultimately winding up a washed up meth head in modesto constantly claiming how great they would have been.
