Dire market conditions have forced virtually all social-networking firms to scale back. In October, the third most popular social-networking site, Hi5, announced that it would cut between 10 and 15 percent of its staff. And in November, the business-focused networking sites LinkedIn and Jive said that they would slash their workforces by 10 and 40 percent, respectively.

Facebook's power derives from what Jeff Rothschild, its vice president of technology, calls the "social graph"--the sum of the wildly various connections between the site's users and their friends; between people and events; between events and photos; between photos and people; and between a huge number of discrete objects linked by metadata describing them and their connections.
