Jack, John and Joe are talking about games.
Jack has played a new game. He likes it. He tells John and Joe, who, knowing Jack's reputation for giving games a fair, balanced review, and that their tastes and his are often similar, decide that it's a game they should try. So, based on Jack's recommendation, they buy the game, as do several other people who have been listening in.
These kinds of conversations are the stuff of legend in the advertising community. Getting a consumer so excited about your product that he'll tell others to buy it is essentially free advertising, and the most effective form besides. Marketers call it "buzz," and they track it as religiously as brokers follow the stock ticker. They even try to create it, by sending trained salespeople, or "shills" into places where normal people congregate in order to get those normal people talking about their product. These days, the tactic has moved online.
Jack, John and Joe are all members of an internet community forum. Their conversation is not taking place in one workplace, but several; each of them is typing his part of the conversation onto his computer and posting it on the forum. Each message is then read by more people in other workplaces, some of whom live across the globe. John and Joe visit the site during their off-hours, or from their desks, when they should be working. Jack, however, actually is working when visiting the site. His job is to post messages to internet forums frequented by people like John and Joe, and to convince them to buy products represented by his employers. Jack is an internet shill.
