examples include Amazon (reviews of reviews) and MyFaveThings Facebook app (users show what they have and what they want so their friends can simply “buy what he bought”). The concept is simply that modern consumers turn to their peers (instead of advertisers) to get ideas (awareness), advice (consideration), and recommendations (choice) during their purchase process. This can come from direct friends, from experts, or from collections of total strangers. The social actions of these groups help move the potential customer closer to the purchase expeditiously.
