A few months back the marketing gurus of GM came up with the idea of having internet users put together their own ads for one of their big SUVs. “Leveraging Web 2.0” and other trendoid-speak is probably how they convinced the suits to go for it. Viewers would take the provided music and video clips and put them together in a Flash file, along with some (hopefully) catchy text copy.

However, I wonder whether or not they predicted some of the interesting results.
