Facebook cofounder to tout "unprecedented growth"Facebook cofounder Dustin Moskovitz took some time to rehearse his Wednesday morning keynote at the CTIA Wireless conference at San Francisco's Moscone Center. No surprises are likely: Moskovitz's presentation, of which you're getting a sneak preview, will talk up Facebook's "unprecedented growth." Executives and board members are tiresomely fond of citing the stat that the social network's user base continues to grow a steady 3 percent a week. Expect, too, some figures on usage of the Facebook's iPhone-optimized wireless site. We're just curious what percentage of U.S. text-message traffic is carrying "pokes." (Photo by Brandee Barker)
