THE FINDINGS: The Wall Street Journal says Facebook's growth appears to be slowing, particularly in the U.S. Unique U.S. visitors rose 5 percent in April to 158 million, the slowest growth rate since comScore started tracking data in 2008.
TIME SPENT: Users spent more than six hours a month on the site in April, up 16 percent from the prior year, but slower than the 23 percent increase in 2011.
THE BACKDROP: Facebook's stock has slid since it went public last month. Investors are concerned about Facebook's ability to keep increasing revenue and make money from its growing mobile audience.
