Facebook’s New COO

Facebook has a big new hire. It’s Sheryl Sandberg, a Google vet who most recently helped lead the search giant’s enormous ad sales operation.

Having experience building a huge sales team from scratch will certainly come in handy at Facebook. More importantly, Sandberg has plenty of experience with changing the online ad game, since Google rose to dominance in search ad spending under her six-year watch. Facebook certainly has its own ambitions in that arena.
