The strategy of viral marketing gets customers to sell a product to other customers on behalf of the company. That often means convincing your friends to climb on the bandwagon, and sometimes you get a cut if they buy something. Some might argue that that means you’re selling out your friends (or at least selling to your friends) in exchange for a piece of the action. Others might say you’re simply sharing the wealth with your buddies. Have you ever passed along names of your friends to a company or website? If so, what happened? How do you feel about this practice?
