Dustin Moskovitz, Mark Zuckerberg's Harvard roommate, recently stopped speaking to him. This has made things awkward at Facebook's Palo Alto campus, as Moskovitz is the last reminder walking around that Zuckerberg was not Facebook's sole founder. The two have resumed talking, but Moskovitz, seeking to dissociate himself from his college chum's creation, had dropped the title of vice president and asked for his bio and photograph to be taken off the company's PR website.
He's now taken the title of "technical lead," and is working behind the scenes on Facebook's infrastructure. (Moskovitz was not always so publicity-shy: He gladly spoke about Facebook's wireless initiatives at the CTIA conference last fall.) Why the split, after they've worked together so long?
