Glad to find this thread again. Had to write a paper on guerilla marketing. Here's a guerilla tactic, that I came across while searching around:

In a campaign set to start Thursday, the U.S. arm of Sony Ericsson Mobile Communications Ltd. will take "guerrilla" marketing to a new level. Its goal: to get consumers to pay attention to the new T68i, a mobile phone that can double as a digital camera.

In one initiative, dubbed Fake Tourist, 60 trained actors and actresses will haunt tourist attractions such as the Empire State Building in New York and the Space Needle in Seattle. Working in teams of two or three and behaving as if they were actual tourists, the actors and actresses will ask unsuspecting passersby to take their pictures.

Well, certain media commentators went into conniptions over Sony Ericsson's tactics. Among the offended is Matthew Lynn, a columnist for Bloomberg News, who blasted Sony Ericsson's guerilla marketers as "human spam."

With all due respect, he just doesn't get it. The urban-youth demo in question, far from being offended, is likely to get a kick out of the marketer's resourcefulness. After all, the actors fit into the environment and those consumers who were genuinely interested in theT68i received useful product information.
