Wiki-Advertising

In a creative new campaign, the good people at General Motors are pioneering wiki-advertising. Ordinary web-surfing shlubs -- like you or me -- can pretend to be Madison Avenue creative types, creating commercials for the gas-guzzling SUV, the Tahoe. You get to choose backgrounds, video shots, music, and then input text. It's a contest, as you might expect, with big prizes for the best entries.

Of course, the internet being what it is, there might be a snarky subversive or two out there who have put together ads that don't exactly put the Tahoe in the best light.
