Another Facebook (FB -0.5%) exec departs: North American sales chief and 7-year company vet Tom Arrix says it's "time for new challenges." His exit comes less than a month after that of EMEA director Christian Hernandez and respected ad product chief Gokul Rajaram. Facebook obtained 47% of its Q1 sales from North America. Q2 results arrive on July 24.
