Greg Benedetto believes in the old adage "the customer comes first." He worked for Canada's HMV record chain for two years as a teenager and, in that time, learned a thing or two about getting people to buy things. "A customer who is treated well probably won't say anything," he says. "But a customer who is treated poorly will tell everyone they know." And that is exactly what Benedetto plans to do if Facebook's new targeted ad campaign gets out of hand. Already Benedetto has invited all 562 of his Facebook friends to join the group Stand Up! Don't Let Facebook Invade Your Social Life With Ads!
