I stumbled over a Chevy ad on the front page of the New York Times today, announcing a dialogue about alternative energy with the headline "We share a planet, why not share a dialogue".  While I appreciate the offer to talk openly about their alternative fuel efforts (and realize I have to do some more research about the seriousness of their efforts), I disagree with their choice of words. After navigating to the microsite, I had to realize all they offer is a Q&A section. The answers seem to be pretty open and address the issues, but technically a Q&A doesn't qualify as a dialogue:  Users can only submit questions, neither are they able to respond to the answer nor are other visitors able to leave their response to the answer or the initial question - Chevy has the final word!
