Seven hundred million of anything is hard to ignore. As Facebook becomes an Everything Hub—the go-to place for gaming, emailing and IMing with friends, watching videos, etc.—it makes more and more sense for brands to enable Facebookers to shop on the site as well. Consumers have always tapped into their social network to get and make recommendations on what to buy, read, eat, see and do. Facebook amplifies that to the nth degree, and a commerce channel on the site adds a social influence to transactions. The “social” in social network can help spread the word about exclusive merchandise and brand and product preferences, and ultimately drive sales.
