ComScore says Facebook traffic dropped in September. We didn't think that was accurate. It turns out that traffic was only "down" because ComScore's measurement panel (along with Nielsen and others) only measures traffic from home. As students return to school, they are removed from the panel and traffic "drops." Facebook says that active monthly users is still rising at 3 percent a week, as it has since January 2007. [GigaOm]
