Facebook (FB -2.8%) mentions in its Q2 10-Q that 103M of its 543M mobile monthly users only accessed its services via mobile devices; that helps explain Facebook's U.S. ad impression drop, and drives home the company's need to improve mobile monetization ASAP. Also mentioned: Zynga (ZNGA -4.1%) made up 14% of revenue, down from Q1's 19%; $633M was spent in 1H on patent acquisitions; and duplicate accounts could make up 4.8% of users (46M).
