The report, based on a Bloomberg and YouGov poll of 1,003 U.S. adults from July 29 to August 2, revealed that 71% percent of U.S. adults use Facebook, but that number will drop to 69% a year from now. Among people who use both services, 30% say they plan to cut the time they spend on Facebook. However, 31% of Google+ users say they've abandoned their Google+ accounts or never posted anything on them.
Twitter and LinkedIn will continue to grow, however.
