Facebook (FB -2.9%) and Zynga (ZNGA -7%) dive following a Capstone Investments report claiming Facebook's U.S. users fell 1.1% over the last 6 months. Capstone adds Facebook's growth was minimal or negative in 14 of the 23 countries in which its penetration rate is above 50%. The report backs up recent data suggesting U.S. saturation, and drives home Facebook's dependence on less profitable emerging markets to drive user growth. (previous)
